Sequence and patterns order of easiness
To identify a pattern in a sequence you should first see if you recognise a sequence straight away. If not you should tackle this in the following order of easiness.

There is a consistent difference of 2 between each number.

There is a consistent difference between the difference of the sequence and that number is 2.

Divide each term by the previous term.
`6/3=2` `12/6=2` `24/12=2` `48/24=2`
