Worksheet Overview

QUESTION 1 of 10

Hello letter detective, it's time for a letter puzzle. Can you help us to solve the challenge below?

 

We are going to look at the alphabet in a different way than you usually would.


In this activity, you will be working out sequences that use letters of the alphabet.


 

 

Here is the alphabet for you to use as a reference:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

 

Take a look at the following alphabetic sequence:
D, F, H, _, L

Which letter is missing between the H and L?
 

First, we need to work out how far each letter is jumping to the next. 

They are jumping two across in the alphabet each time.

 

So, if we jump two letters forward from H, we land on J.

We can check this is the right answer by going backwards two from L. 

 

It is definitely J! This is because J is two letters after H in the alphabet and two letters before L. 

So, the sequence would be: D, F, H, J, L, etc…

This sequence follows the order of the alphabet when it is written backwards. Hopefully, you noticed this detective! There is a jump of two letters backwards each time. So after W, if you jump two letters you reach the letter T. Remember alphabet sequences can be in forward or reverse (going backwards) order.
