Letter detective, we need your help! In this activity, we will be using the alphabet to help us crack a letter code!
There are many different types of sequences. In letter pair sequences there are pairs of letters joined together by a common theme, normally the amount of space between them. Some follow a forwards sequence, while others follow a reverse alphabet sequence.
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 sequence:
US is to QO as MK is to ___?
First, we have to work out how the first letter of the first pair (US) gets to the first letter of the second pair (QO).
To get from U to Q, we jump 4 places to the left.
Then we have to work out how the second letter of the first pair gets to the second letter of the second pair.
To get from S to O we also jump 4 places to the left.
This means we need to do the same to the letters M and K to work out the missing letters in our sequence.
This makes our missing letters IG.
So the answer is:
US is to QO as MK is to IG.
Let’s try another:
TR is to SU as BL is to ___?
To get from the first letter of the first pair to the first letter of the second pair, we jump 1 place to the left.
To get from the second letter of the first pair to the second letter of the second pair, we jump 3 places to the right.
This means we need to jump one place to the left from the letter B, giving us A and then three places to the right from L, giving us O.
So the correct answer is:
TR is to SU as BL is to AO.
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.
