How is the series running ?
What's the difference between each term and how would you express that as an equation ?

Assuming start state at 16:

Nth=16+((n-1)*7)

We help people with homework, we don't do it for them.

On a side note: That's an interesting way of writing the series. Haha. It works though.

Well, the general formula for an arithmetic progression is:

T_n = a + (n-1)d

So, it's easy substituting the first term a, the common difference d into that formula. :)
