Worksheet Overview

In this worksheet, you will learn how to spot the missing numbers in a given sequence.

Example 1

Can you fill in the missing numbers in the sequence below?

Answer

First, we must look for clues from neighbouring terms to work out the rule.

Here 51 - 39 and 39 - 27 both equal 12.

This means that the rule for the sequence is that each term goes down by 12.

B will be 51 + 12 = 63.

A will be 63 + 12 = 75.

Now, let's put this method into practice!
