pattern

When trying to find a pattern, we look for something repetitive, or we look for a rule which tells us how to continue the pattern.

For example, the numbers 3, 8, 13, 18, 23 and so on follow a pattern. The rule is start on the number 3, and then add 5 each time.

A tessellation is an example of a pattern made from different shapes. This picture in an example.
