I just spent two days in class trying to learn recursive sequences and I didn't understand it but somehow this guy on the internet taught me it in less than 10 minutes. HOW. IS. HE. THIS. GOOD. AT. TEACHING.
Thank you this really helps, I am currently taking a math class right now and the teacher doesn’t even take notes and he is very uncommunicative, so it is hard to figure out how to do the math, but everyone else in the class gets it
You need to do a video on solving these, and/or a discrete math series! It gets a bit confusing to solve. My last assignment was proving the Fibonacci sequence, which is cool, but a little challenging.
I'm here for my Math 232 class, but that last little statement applies to more than just math (for myself, Comp Sci 250). Explicit code is very direct, but will take forever (hyperbolically) if the correct problem comes up, so the solution is to use a recursive code with a beginning term. Cool
Thanks, my teach went over this in 20 minutes, that may seem like a good amount of time, but do that, with only 3 problems, and him not fully explaining how it is done, or what explicit, and recursive equations are! (Don't get me wrong he's a great math teacher, but he needs to explain a few things more. Instead if hinting at what something is.)
This increasingly disgusting, bad habit teachers have wasn't a thing in the 70s or 80s, since the iNet was in its infant stages. I'm trying to get more oversight on bad teachers and how to remove them, but evidently, this process is also in its infant stages or doesn't exist at all.
Not really my grade rn is a 75 barley passing so just do your homework and sit next to the teacher in class like I do so you can be sure to hear what they say
Ok so the explicit for me looks like f(n)=-6+5n and recursive was an=an-1+5 soooooo I'm hecka confused here and I have math first hour and I've been studying all weekend. And I was supposed to be celebrating my late bday today and ended up studying for my 5 FINALS TOMORROW....love that
Ok so I like how you worked but we're learning recursive a little bit differently. I'm totally lost with the recursive equation and I think I get your way but trying to turn your way into ours is giving me some difficulties.
Thank you. I understand it now. But I have a question. I can't get the recursive formula of 5, -10, 15, -20, 25. I have tried this several times to get this formula. Can you help me?

Shoutout to all the other people failing math who came here to try to get help and got more confused
same and thanks for the shoutout
i came here since my teacher is too lazy to teach & tells us to come here :-)
Bob Chlarson I’m not failing xd😂. Just needed clarification bc I’m taking algebra in 7th grade.
SOCCER IS LIFE
Lol that means me
Wait, this is precalculus? I'm learning this in Algebra I. Wtf.
Chocolate & Twix Bar Now precalc is the same as algb 1 Lmfaoo
you mustve been in an honors class lol
Same
SAME i have this is algebra 1 honors btw im a freshman
I take this for algebra 1 too lol
I’m in an honors class as well
I’m in 8th grade
And then satan said: " put the alphabet in math!"

Did you tell the doctor? Im sure he has a pill for that
He did
"You can find every other term in terms of the term before it." :D nice

wait arent u supposed to take notes not the teacher?..
I think you might have my teacher
I am now more confused
i agree
Dan Talks you are VERY wrong
SAME!!! 2019!
stfu noob
OMG now I understand THANK YOU SO MUCH I emailed my teacher so THANK YOU I DON'T NEED HER HELP ANYMORE :)))))
Thanks, I was struggling to understand this on my homework and this helped a lot.
I found how to do this. Lol God bless :D

I swear to god I’m just gonna get a bunch of math books one summer and study up to precalc so I never have to deal with this again

this man saves my life every time
Thank you! It was quite a search to find a youtube video that tells the difference between recursive and explicit.
I started my test yesterday and I'm now watching this before school the next day so I can pass it
This is a supremely helpful video. thank you!
i came here since my teacher is too lazy to teach & tells us to come here :-)
no one? ok
hello lol

Thank you so much! This really helped! The way we do it we substituted k to n so it kinda confused me a little but now I got it!
You make this so easy
Thank you!
POV: it’s 5am on a Sunday during covid virtual school and you’re cramming for a cumulative precalc exam due at the end of the day :)
Precalc exam? I'm doing this in algebra 1
I thank you for getting me through middle school
I don't know if it will help anyone, but learned it as F(n) and not A(k). Should't make a difference, but it's a bit confusing at first.
Thank you, i was genuinely very confused on where A(k) came in my homework.
thank you! you just answered what i was looking for :D
"This is not an attractive color"
lmao 😂
i got a 47% on my test so now Imma retake it and actually study
I understand recursive quite well and I must say that this made no fucking sense.
Im saying !!
Well then you didn't understand it well enough.
Feels good to know 900k + come here to study with me :)
Can you help me w/ this? My question is find the explicit formula of 4,8,12,16,20
OwU no
Link to respective playlist on khanacademy website, please!
Can anyone tell how is this finna keep me living or help in life
no, no one can cause it cant 😭
Me, when I have a quiz on this tomorrow and still don't know absolutely anything
This is gonna help me on my test Tomorrow because I don’t pay attention in class
Have been doing this topic at college. We call them deductive and inductive definitions though rather than explicit and recursive :)
1:07 downhill from here
khan academy my beloved
thanks for this explanation! the textbook I'm reading was not clear on the recursive definition!
this did not help
He makes this sound way too complicated.
Anyone here cause school got shut down
shout out for the 8th graders at BASIS wallowing in regret
love this guy
This video is algebra 1 not precac so that's why you guys are confused. Its off topic
Advanced Algebra, is when the formulas are learned
I'm in pre algebra and we are learning this and I understand it now
It actually is precalc since it comes up again in Cal 2.
yeah i’m in algebra 1 rn
U saved my life
Thank you so much!

Okay. What I learned was
An=An-1+d but the 1 is tiny it's the size of the n

omg thank you so much, I understand
I only in seventh grade doing this
sounds like younger by your English
RagtagNinjaboy Not everyone on the internet speaks English their first language.
Chris S Me too!!!
wtf thats horrible i am so sorry
hi_frwend i laughed so hard when i read this
I understand how to do recursive just fine. and this was very different. I just wanted to know how to make an explicit function
I have a math test today and I failed the practice test. Please help
Edit: I failed 🧍♀️
LMAO
What happens now? Is there still hope for your mathematics journey?
@@HereForTheComments school’s out 😎
@@00777_ Did you pass the grade?
@@HereForTheComments yep I did well on all the other test this one just messed me
Thanks 😊
YESS, we love just still not getting it
Very helpful thank uou
Do you guys have any tips for raising your math grade?
Not really my grade rn is a 75 barley passing so just do your homework and sit next to the teacher in class like I do so you can be sure to hear what they say
Bruh i slept on my online class in math and i have a test later and watching this now
Thank you
failing math during quarantine squad?
biig yeeees
Ok so the explicit for me looks like f(n)=-6+5n and recursive was an=an-1+5 soooooo I'm hecka confused here and I have math first hour and I've been studying all weekend. And I was supposed to be celebrating my late bday today and ended up studying for my 5 FINALS TOMORROW....love that
Can you make a video on how to be good at math because my brain just don't agree with Math because its hard tnx.
The way there’s 1M views but only 2K likes, just shows how many times ppl had to re-watch it 😭
I hate math but I love his videos
My mind is explode right now , but it's okay . I'll rewatch until i understand it .
I have a test on this today. We’ve been learning this since Monday and I still don’t understand
thank you!
well i understood.
(k-1) what is the use of -1?
Put it in double playback speed and you can learn everything about math in like 2 days
This made it harder and made me confused

or ours into his way. He needs to work it the normal way :(

Why isn't there a single video on RUclips of someone doing a quadratic version of this?
Thank you. I understand it now. But I have a question. I can't get the recursive formula of 5, -10, 15, -20, 25. I have tried this several times to get this formula. Can you help me?
No, its alright :) I already know it :)

Your so dumb that's easy
@@saiharinathnerella501 you're*
-2(n-1)
thx man
so you shows ak-1, but what if the formula says ak+1, what does that mean? the next term? if its recursive how can u being going off of the next term?
That's crazy who here cause of corona?
What if you don't have your first term or difference but you have the number of terms?
I kinda understand it but how to get the next term when the differences are not the same?
haha i’m a year late but if they’re not the same then it’s not a arithmetic formula
There are no bad explanations, only students who refuse to ask when they don't understand something. ;)
had to turn in a test today with literally nothinf kn the first page cus i cant do thus yet 😭
Wha .. ? WHAAA ??

khan: "that's not an attractive color, let me write this in.."

I don't think he meant it like how you think he meant it
Ay thanks for the help but pretty sure i still bombed the test
You have a high IQ
Question: is there always a -1 in the (k-1) part or what?
what is it mean "one less than the term we add"..?
To find the mean you add all the terms together and then divide by the number of terms
Why does he put a (k-1) after the three?
Please answer.
+rusko dudesko no. Just no
What book are u using??? can someone tell me?
He sounds like Young Don the sauce God
hold up, this is pre-calucus?? Im learning this is algebra...
Same :/
I gotta test Tommarow and I’m not consuming any of this information
Could I not say for the second one; 3k + (k-1)?
Lol what?
what. this is nothing like in school. now i cant do anything while im sick

Where did they (k-1) come from 😭
Is previous term always -1???
