## Topic 2: Number patterns    For these questions, you need to identify the pattern, and then continue it.

Look at this number pattern:

406, 410, 414, .... , ....

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

Next you need to work out how much is being added each time. This is an add 4 pattern.

So by adding 4 you can work out the next two numbers in the pattern:

406, 410, 414, 418, 422

Here is another number pattern:

259, 256, 253, .... , ....

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

Next you need to work out how much is being subtracted each time. This is a subtract 3 pattern.

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

259, 256, 253, 250, 247

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.

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

Look at this pattern:

3 900,  4 500,  5 100,  .... ,  ....

4 500 - 3 900 gives you the difference.

4 500 - 3 900 = 600

The pattern is an addition pattern (the numbers are getting bigger), so you add on 600 each time to complete it.

3 900,  4 500,  5 100,  5 700,  6 300
