In this series of videos I continue to extend the work I did earlier on using sigma notation to represent the summation of a series. This video is partly a reminder of that work and then introduces you to the following results based on summing linear terms.

Formulae to remember:

In this video I continue to extend the work I did earlier on using the standard results that I showed in the previous video, and based on these results show you how to tackle the following problems which I would strongly encourage you to try.
Each one I have chosen to reflect something different.
