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.* Aimed at students in their final two years of high school.* Studying mathematics is best done by working through examples and exercises.
There are many interactive examples and exercises in this tutorial that must be completed to achieve 100% progress.* Written by a Maths teacher with 20 years of teaching experience.* Completely free (no Ads).* Works without internet so that you can learn Algebra while travelling in the train, bus etc.
