I have no idea. I am allowed to use MAPLE, but the command sum(expression,m=1..M) doesn't give a general solution in a polynomial form, so I am quite confused. And we haven't gotten to sequences and series in my calculus course yet.

I have no idea how to prove it, but this formula is what you are looking for. It says . Put n=2M+1 and you get .

Notice that the sum goes from 1 to 2M. But using the fact that you can see that this is twice the sum from 1 to M.
