A number sequence is a series of numbers written in such a way that each number in the sequence can be got by following a given rule. For example, in the sequence 4, 16, 64, 256, ... each number in the sequence can be got from the previous term by multiplying by 4. In this case, the rule is: multiply by 4. The numbers in a sequence are called 'terms': in 4, 8, 12, 16, ... '4' is the first term and '12' is the third term.
