A number sequence is a list of numbers that are linked by a rule.
If you work out the rule, you can work out the next numbers in
the sequence. Below are some examples:
a) The rule is to add 6 each time.
So the next number would be 27 + 6 = 33
b) The rule is to multiply by 3 each time.
So the next number would be 54 x 3 = 162
