Part 1: Introduction

Sequences are a collection of numbers which follow a pattern to get to the next number.

A term in a sequence is one of the numbers. The terms are numbered 1, 2, 3, etc.

Examples include:
 * 1, 2, 3, 4, 5, 6, 7...
 * 1, 2, 4, 8, 16...

 Types 

So now that we've covered the basics, let's move on to the types of sequences, them being:


 * Arithmetic sequences 
 * You add a constant (d) to the previous term to get the next term in the sequence.
 * Example: 1, 4, 7, 10, 13, 16...


 * Geometric sequences 
 * You multiply a constant (r) to the previous term to get the next term in the sequence.
 * Example: 1, 2, 4, 8, 16, 32...
