Algebra Tutorial 20

Given a sequence, we can form the sum of the first n terms of the sequence, for each positive integer n. This sequence of sums is called a series.

In this tutorial, we look at summation notation for sums, and we derive formulas for the sum of the first n terms of arithmetic sequences and geometric sequences.
