Answer nku HHAHAHA
1) 7,13,19,_,_ = 7,13, 19, 25, 31
2) 1,3,9,27,_ = 1,3,9,27,71
3) 160,80,40,20,_ = 160,80,40,20,10
4) What is the 9th number in the sequence 9, 13, 15,21,?
=9,13,15,21,25,29,33,37,41=The 9th term in the sequence is 41
5) Find the 8th number in the sequence 9,4, negative 1, negative 6?
=9,4,negative 1,negative 6,negative 11,negative 16,negative 21,negative 26
=The 8th number in the sequence is negative 26
Try2 lng nah sir, ambt kung correct HAHHAA

Sir paano po kapag yung 1st term eh letter?

[@mathusaymathtutorial935]

Can you give the specific sequence? Para makita natin ang patterns ng sequence. If letters ang terms sa sequence, ang technique jan ay do skip counting.

[@claire-el4fl]

sir ano yung pattern ng face expression? can you describe the pattern and also what is the pattern of arrows pointing in all directions and also polygons increase the number of side??

[@mathusaymathtutorial935]

Sa example na emojis, alternating happy and sad faces lang yun. While for polygons naman, as we know, polygons are closed figure and magstart tayo sa triangle... 3 sides, 4 sides, 5 sides,... and so on...
This can be generalized as n + 2... dahil each term after the first nag increase lang ng 1 side. that is if ganyan ang pattern....
For arrows pointing in all directions, tignan mo lang ang orientation ng given figure... usually naman pag figure mas easy mag detect ng patterns

[@claire-el4fl]

Yes ganun nga yun sa polygon , n + 2 ba yung pattern?yun bo ba minimean niyo sa n + 2

[@mathusaymathtutorial935]

@@claire-el4fl yes po. Kasi the sequence 3,4,5,6,7... will hold if our function is n +2 po.

[@claire-el4fl]

And also meron din po mga triangle na nagaadd based on odd numbers, pwede po ba the number of triangles gradually increases in consecutive odd numbers? Or may mas pang tamang name ng pattern for that?

[@claire-el4fl]

Also sir what to do you call pag yung mga numbers sa sequence 1,4,9,6 is it the numbers are all perfect square or cube numbers??

@@mathusaymathtutorial935 sir paano niyo po malalaman ang last term?

[@mathusaymathtutorial935]

@@celinejoyjavier771 usually, hinahanap natin ang nth term or general term para makuha ang last term... But if alam mo nang mag identify ng ibat ibang uri ng sequences then may mga formula tayong pwede gamitin... Please check yung mga kasunod na vids nito to know more about this!
