First term has n=1. The first term is 2.

The other terms you find the same way.

Common difference is 2. Any term in an arithmetic sequence in general is like A%5B1%5D%2Bd%28n-1%29. The common difference is d.

its common difference d=
Term of an AP: a%5Bn%5D+=+a%5B1%5D+%2B+%28n+-+1%29d, with:

a%5Bn%5D = nth term in the sequence

a%5B1%5D = 1st term

d = common difference



a%5Bn%5D+=+2+-+2%28n+-+1%29

Starting you off, 

Use the formula to find the other terms
