Worksheet Overview

QUESTION 1 of 10

Number detective, you’ve arrived just in time!  

We’re faced with a new puzzle and we hope you can help us solve it.  

 

Can you work out which number comes next in this sequence?

6, 8, 10, 12, 14, __

 

Did you get 16?

 

This is an even number sequence and the next even number after 14 is 16.

 

Even numbers are numbers which end in 2, 4, 6, 8 or 0.


 

Which number is missing from this sequence?

3, 5, 7, __ , 11, 13

 

This is a sequence of odd numbers and the missing odd number, between 7 and 11, is 9.

 

Odd numbers are numbers which end in 1, 3, 5, 7 or 9.


 

Sometimes, sequences may go up or down in multiples from your times tables.

 

Which times table does this sequence form part of and can you figure out which number comes next?

3, 6, 9, 12, __

 

This is the three times table and the missing number is 15.



It’s now your turn to find the missing numbers. Good luck number detective! We are counting on you...
