## Topic 2: Number patterns

For these questions, you need to identify the pattern, and then continue it.

â€‹

Look at this number pattern:

â€‹

30, 33, 36, .... , ....

â€‹

The first thing to notice is that the numbers are getting bigger each time, so this is an addition pattern.

â€‹

Next you need to work out how much is being added each time. This is an add 3 pattern.

â€‹

So by adding 3 you can work out the next two numbers in the pattern:

â€‹

30, 33, 36, 39, 42

â€‹

â€‹

â€‹

Here is another number pattern:

â€‹

86, 84, 82, .... , ....

â€‹

This time the numbers are getting smaller each time, so this is a subtraction pattern.

â€‹

Next you need to work out how much is being subtracted each time. This is a subtract 2 pattern.

â€‹

So by subtracting 2 you can work out the next two numbers in the pattern:

â€‹

86, 84, 82, 80, 78

â€‹

â€‹

If you are not sure how much is being added or subtracted in a pattern, you can find out by calculating the difference between any two numbers that are next to each other.

â€‹

Difference is calculated by subtracting the smaller number from the bigger one.

â€‹

Look at this pattern:

â€‹

47,  53,  59,  .... ,  ....

â€‹

53 - 47 gives you the difference.

â€‹

53 - 47 = 6

â€‹

The pattern is an addition pattern (the numbers are getting bigger), so you add on 6 each time to complete it.

â€‹

47,  53,  59,  65,  71
