# Math Help - Am I right? (Sequences question)

1. ## Am I right? (Sequences question)

The question is:
"Find a formula for the general term an of the sequence, assuming the pattern of the first few terms continues."
{2,7,12,17, ...}

a_n = 5n - 3

a_(n+1) = a_n + 5

So, am I right?

Any input would be greatly appreciated!

How about posting the actual sequence?

The book's answer is: a_n = 5n - 3

My answer is: a_(n+1) = a_n + 5
Your text book gave the closed form.

But in order for your answer to be complete, you must add $a_1=2$
