Question

Write a recursive formula for the sequence 5, 18, 31, 44, 57, … Then find the next term. help pls! Will award medal!!!

Answer 1

\[t_n = t_{n-1} +13\]

Answer 2

If the sequence is
5, 18, 31, 44, 57, …
Than we are adding some number to each step.

\[a _{n}=a_{n-1}+d\]
an= nth term in sequence
an-1=term before the nth term
d= common difference

Answer 3

^^^ So what @royalranger said would be correct :D

Answer 4

@sunnnystrong equation works just as well. I think you can find the last term.

Answer 5

In function notation:
t(n)=t(n-1)+13

Answer 6

ah I get it.. So then t(n) = 5+ 13 (n - 1)

Answer 7

the next term is 70 right?

Answer 8

Yes it is 70.

Answer 9

yep!

Answer 10

good job @logo :)
