Core Mathematics - Summing up arithmetic sequences

Summing up arithmetic sequences

* A sequence is arithmetic if it has a common difference between each of
its terms.

You can be asked to find

* a particular term

* the number of terms

If given two pieces of information, you can be asked to find a and d by
using simultaneous equations (remember RAWFESSA).
