#### Worksheet Overview

In this activity, we will learn how to fill in the missing numbers in given sequences.

e.g. Fill in the missing numbers in this sequence:

 A B 51 39 27

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.

So the final sequence is:

 75 63 51 39 27
