Do you understand what is meant by partial fraction decomposition? . I suggest you now write out the first few terms using this and see what happens. It also might help to review your classnotes or textbook. Telescoping series would be a good place to start.

Okay..
I think i found a pattern in the first few terms, as i get
so that means cancels eachother out meaning the sum is 1.
Then for the alternating series, it gets timed by -1, and by the same idea it sums to -1?
