Here's my problem: 1 * 2 + 2 * 3 + 3 * 4 + . . . + n( n+ 1) = n(n + 1)(n + 2) / 3(adsbygoogle = window.adsbygoogle || []).push({});

3. The attempt at a solutionI know that there is a Basis step and Induction step. For the Basis step I have the following but don't know if I'm on the right track: Basis Step 1 * 2 = 1 * 2 * 3 / 3 , which is true

I get lost at the Inductive step.

Any help would be appreciated
