Question

royalranger · Answer

$$t_n = t_{n-1} +13$$

sunnnystrong · Answer

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

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

royalranger · Answer

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

sunnnystrong · Answer

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

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

the next term is 70 right?

royalranger · Answer

Yes it is 70.
