Number Patterns

UK Primary (3-6)

Describe a pattern (add/sub)

Lesson

If you saw a list of numbers like $7$7, $10$10, $13$13, $16$16, $19$19, you might notice that there is a **pattern** to the numbers. To get from each number to the next, you need to add $3$3. We say that the numbers are **increasing by $3$3**, or that you are **adding $3$3 each time.**

This is what we call a **description of a pattern**. Watch the video below to learn more about describing patterns!

Now that we've learnt how to describe a pattern, try some questions yourself!

Describe the number pattern below.
