I cant' Edit, so I repost the problem: Q: What is the a8 term of the sequence [an] if [an] equals a.) 2^(n - 1) ? b.) 7? c.) 1 + (-1)^(n) ? d.) – (-2)^(n) ? I am confused on what to do here?

ok thanks....so all you do than really is whatever n is, you put that number in the equation. I see. Thanks.
