Check list:

Patterns: Investigate number patterns including those where there is a constant second difference between consecutive terms, and the general term is therefore quadratic.

There are a couple of sections where you can feel your brain stretching and this is one of them. It is possible to find the general term of a quadratic sequence without the steps in these videos, but it is a lot more challenging! Simultaneous equations will help you a lot in understanding how to find the general term.
