General arithmetic sequence term is a%5B1%5D%2Bd%28n-1%29, where n is a natural number, the index of a term. Based on that, what can you say about the term at n=5? Can you find a formula for the first n terms of an arithmetic sequence? Maybe refer to your book, or derive it yourself?

You should find that the sum of the first n terms of an arithmetic sequence is %28n%2F2%29%28a%5B1%5D%2Ba%5Bn%5D%29.
