I’m doing a induction proof and need to find a way to prove (k(k+1)(k+2))/3 + k + 1 = ((k+1)(k+2)(k+3))/3.
thanks

Are you sure the statement is correct? I plugged in k=0 and k=1, and the statement isn't true.

Yes, please, post the problem in it's entirety and maybe we can help.

If k=-1 then it is possible

This post is over 3 years old. I believe it's rather a moot point by now.
