Hello, I've read everything I can on induction for the most part it makes sense, but I'm having trouble with this summation problem:
SUM from i = 1 to n: (-1)^(i+1)(i^2) = [ (-1)^(n+1) n(n+1) ] / 2
(I dont know latex...yet)
1 = 1 check
plugging in n+1 and trying to solve I can't seem to get anywhere...
Please point me in the right direction
Thank-you for any help!!
