Arithmetic & Geometric series Proof Cheat Sheet
This is a short and sweet cheat-sheet to help you to understand and remember the summation formulae for an A-Level pure mathematics exam. The document shows a clear step-by-step proof of the sum of an arithmetic series and the sum of a geometric series. There are also some extra bitesize details about a periodic sequence (The other type of sequence present on the WJEC spec) and the difference between convergent and divergent sequences.
