As children progress through KS2 they will learn more about number sequences in Maths. As well recognising simple number sequences of increasing value they will also be exposed to decreasing sequences in more complicated steps, such as patterns decreasing by 25 each time. They will also learn more about odd and even numbers and the patterns made when adding or subtracting them from one another.

Recognising patterns in number sequences is all about finding out what comes next in a row of numbers. For instance, do you know which number should follow this sequence 20, 15, 10, 5? Well, the numbers are decreasing. or getting less, each time. Each number is 5 less than the one before it. To find the next number in the sequence we need to take 5 away from 5 which will give us the answer 0.

See how much you have learned about recognising patterns in number sequences by playing this quiz for 8-9 year olds.

1.

Which is the next odd number after 151?

152

153

155

160

151 + 2 = 153

2.

Can you find the rule of this sequence? 50, 75, 100, 125, 150

The numbers increase in 20s

The numbers increase in 25s

The numbers increase in 5s

The numbers increase in 10s

Each number (except the first) is 25 more than the one before it

3.

Can you find the rule of this sequence? 125, 127, 129, 131, 133

The numbers increase in 2s

The numbers increase in 3s

The numbers increase in 5s

The numbers increase in 4s

The sequence would continue: 135, 137, 139, 141... etc

4.

What are the next two numbers of the sequence? 4, 8, 12, 16

18, 20

20, 22

20, 24

20, 26

The numbers are increasing in 4s

5.

Can you find the rule of this sequence? 5, 8, 11, 14, 17

The numbers increase in 2s

The numbers increase in 3s

The numbers increase in 5s

The numbers increase in 10s

Each number (except the first) is 3 more than the one before it

6.

What is the next number of the sequence? 140, 130, 120, 110

90

95

100

105

The numbers are decreasing by 10

7.

Can you find the rule of this sequence? 45, 35, 25, 15, 5

The numbers decrease in 2s

The numbers decrease in 3s

The numbers decrease in 5s

The numbers decrease in 10s

Each number (except the first) is 10 less than the one before it

8.

Every second number starting at 2 is even

9.

What is the next number of the sequence? 136, 140, 144, 148

150

152

154
