Sum of the squares of "n" Consecutive integers - Simple Proof

In this video I show the proof for determining the formula for the sum of the squares of "n" consecutive integers, i.e. 1^2 + 2^2 + 3^2 +.... + n^2. This is a pretty abstract proof and makes use of the useful "telescoping" or collapsing sum which I illustrate in the video. The formula for the sum of squares comes up very often in calculus so it's a good idea to understand the proof!
