An arithmetic sequence has the formula:

$\displaystyle U_n = a + (n-1)d$

where

- $\displaystyle U_n$ is the nth term
- $\displaystyle a = U_1$ is the first term
- $\displaystyle n$ number of terms
- $\displaystyle d$ is the common difference

In your case the common difference is 18-10 =**8**

The first term is**2**

the number of terms is**10**

Sub those in and solve
