So you could say that the nth term is just the (n1)th term plus n. But this may not be what you are seeking. Let's write it another way:
So really, S(n) is the sum of the first n natural numbers. Can you think of a way to express the sum of the first n natural numbers in an easy formula? Here's a hint:
