Letter detective we need your help! In this activity, we will be using the alphabet to help us crack a letter code!

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**

Now look at the following letter sequence:

**E** is to **F** as **Y** is to ___.

First, we have to work out how the letter **E** gets to the letter **F**.

We can use the alphabet above to help us work it out.

From **E**, we have moved one place to the right to reach **F**.

This means we need to do the same to the letter **Y** to work out the missing letter in our sequence.

This makes our missing letter **Z**.

So the answer is:

**E** is to **F** as **Y **is to **Z**.

Let’s try another:

**A** is to** C** as **F** is to ___.

First, we have to work out how we get from the letter **A** to the letter **C**.

If we look at the alphabet above, we can see that we need to move 2 places to the right.

So we need to do the same with the letter **F**.

And the missing letter is **H**.

So the answer is:

**A** is to **C** as **F** is to **H**.

In this activity, you will need to be a sequence superstar and complete the letter pairs.

Pssstt!! Here’s a handy hint to help you reach superstar status:

Remember to use the alphabet line to help you work out the code.
