Generating sequences

To generate sequences, we first need to understand what makes a sequence. A sequence is a set of numbers arranged in a specific order, with a set rule to get from one to the other.
We start by picking a number, n. We then apply the given rule to n, to get the next term. With this new term, we apply the rule it to get the third term and so on and so forth.

Examples of sequences

2,4,6,8,10,… Rule – Multiplying by 2.
4,13,40,121,364,… Rule – Multiply by 3 then add 1.
100,95,90,85,80,… Rule – Subtract 5.
