Worksheet Overview

QUESTION 1 of 10

 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

 

 

Answer:

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
