**The following activity is a practice exercise to help you measure your success under timed conditions. **

**If you are unsure of an answer move on to the next question. You should come back to questions you found difficult at the end if you have time. **

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**

Look at the following letter and number pair sequence:

**F45 is to G43 as J37 is to ______?**

First, we need to work out how the first letter becomes the second letter.

The letters are moving one place to the right in the alphabet.

Now we need to work out how the first number becomes the second number. This happens by **subtracting two** each time.

So we need to add one letter to **J **and **subtract two** numbers from **37 **to get **K35**.

So the answer is:

**F45 is to G43 as J37 is to K35.**

**Now it's time to begin this practice exercise. Good luck!**
