[@Abyss777]

@@Cognitoedu can you also make a video on complicated sequences.. like in which the common difference isnt the same for all the terms... I hv prblm finding the nth term of that.. if u can, that would be helpful!!!

Mr you are the best teacher ever in my life thanks mr

[@misterbaleize]

Without doubt the most comprehensive (and simplest) explanation on the internet - thank you!

[@Cognitoedu]

Thanks misterbaleize glad it was helpful!

[@FireWarrior177]

Thank you so much!! This kind of easy to understand content helps a lot, especially in a subject like mathematics. Mathematics is a broad subject and if you don't understand the basics or the simplest ways to solve the problem, you would easily lose confidence and be demotivated. You'd be more likely to quit and just shut down everything and sleep. When I attend classes to learn a lesson, I feel like it doesn't help me a lot. There's chaos, gossip, some students understand stuff before you do (which can easily make you feel inferior/weak in that subject) and it's not always the perfect environment to ask the teacher questions. I know we are supposed to clear any doubts we have by asking the teacher but it doesn't always work out. So, this kind of content by Cognito helps millions of students who struggle, not kidding!! Thank you to Cognito and the teachers, the content creators, the animators, the editors and the whole team in general. I really appreciate what you all are doing! Keep it going!

[@hafsaabdi7338]

Ok, I ain't in my GCSE's yet, but I discovered this channel in year 7, and it helped me pass my physics exam 😅 I lowkey never knew they extended onto other subjects 😂 😊😂😂

[@archish405]

Another way to solve this is using the formula a(n-1)d , where a= first term, n= nth term and d= common difference. But it will only work for arithmetic sequences.

[@Asserhazem-ip7hh]

I share your videos to every one

[@just4467]

out of the 7 videos your video was the only one that helped me

[@EK.editscc]

This is like the best explainer videos for edexel GCSE

[@tejaschanchal763]

Wow I knew a method to find out nth term for arithmetic sequences, but it involved making a table of values with the sequence and the nearest n term. For example if I had 5, 9, 13, 17 I would try 4n which is 4,8,12,16, and then I would know that it is 4n+1. However my method sometimes had me getting stuck, but this method is infinitely easier and faster!!! Thank you for showing us this method, loving your videos on math, physics and chem. Good luck with future videos!!

Thanks Tejas, glad to hear our videos could help! 😊

You can also with the sequence, do this:
1.Find the difference
2.Below that, write the times table of the difference
3.Find out how from the times table you get to the sequence

[@roselynm646]

Can you help out with this one pleeeaaase?
Here’s the sequence.
The third term of the sequence is 11.
….. ….. 11 …..
The rule for this sequence is ‘add four to the previous term then divide by two’.
Work out the first term of the sequence.

You explain this way better than my maths teacher
