You may not have realized but patterns have a rule that you follow to work out the next number, Let's look at how to write rules to describe patterns.

Apply

Complete the pattern:

$6$6, $8$8, $10$10, $\editable{}$, $\editable{}$, $\editable{}$
What is the rule for filling in the pattern?
Add $2$2.
A
Add $3$3.
B

Remember!

Think about how the numbers are changing to work out the rule. Are the numbers getting bigger or smaller, and by how many?

Identify patterns in a multiplication chart and explain them using properties of operations. For example, in the multiplication chart, observe that 4 times a number is always even (because 4 x 6 = (2 x 2) x 6 = 2 x (2 x 6), which uses the associative property of multiplication) or, for example, observe that 6 times 7 is one more group of 7 than 5 times 7 (because 6 x 7 = (5 + 1) x 7 = (5 x 7) + (1 x 7), which uses the distributive pro
