Hi all,

Firstly let me say, I don't know what I would do without this forum helping me learn.

Now, I have only done one example of proving summations by induction, and this one just confuses the heck out of me. Obviously, I know that I have to have a base case, induction hypothesis, and an induction step, I just don't know how to apply it all to this particular proof. Thank you for anyone who can explain this to me.
