# KS2 Maths Quiz - Number Sequences (Year 4) (Questions)

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.
