Okay giving it a go, please tell me where I went wrong. (Do you like the confidence?)
Let p(n) be the statement 2+4+6+...+n=n(n+1)
2=1(1+1) Basic step... That can't be right because if I use 2 for the first n, wouldn't I have to use it for all the n's? Or because the questions uses the first even number is it correct?
Help please before I try to move on and really mess it up.
