This video is all about algebraic proof and forms part of the playlist on algebra proof.

The question is aimed at around grade 7+ GCSE maths and, as always, it's more difficult to understand ... than to actually do.

Prove that the sum of the squares of any two consecutive integers, is always an odd number.
