## Description

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.<br><br>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.<br><br><br>* Aimed at students in their final two years of high school.<br><br>* 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.<br><br>* Written by a Maths teacher with 20 years of teaching experience.<br><br>* Completely free (no Ads).<br><br>* Works without internet so that you can learn Algebra while travelling in the train, bus etc. Internet only required for links to privacy policy and other tutorials. <br><br>* Made with GameMaker (www.yoyogames.com)<br><br>* Only a 14 MB download.
