 # Find Alphabet Sequences Using Single Letter Pairs Moving Forwards and Backwards

In this worksheet, students will solve alphabetical sequences involving single letter pairs in a forwards or backwards motion. It will develop students’ problem solving and sequencing skills. Key stage:  KS 2

Curriculum topic:   Verbal Reasoning

Curriculum subtopic:   Letter Connections

Difficulty level:   ### QUESTION 1 of 10

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:

AD is to DG as GJ is to ___.

?First, we have to work out how the first letter of the first pair A(AD) gets to the first letter of the second pair to the letter D(DG).

To get from A to D, we jump 3 places to the right.

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 D to G, we also jump 3 places to the right.

This means we need to do the same to the letters G and J to work out the missing letters in our sequence.

This means our missing pair of letters is JM.

AD is to DG as GJ is to JM. Let’s try another:

DF is to HJ as PR is to ___.

First, we have to work out how the first letter of the first pair (DF) gets to the first letter of the second pair (HJ).

To get from D to H, we jump 4 places to the right.

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 F to J, we also jump 4 places to the right.

This means we need to do the same to the letters P and R to work out the missing letters in our sequence.

This makes our missing letters TV.

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

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

• Question 1

Here are two letter sequences that both follow the same pattern:

AB is to CD as GH is to ______ ?

 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
IJ
EDDIE SAYS
Each sequence has letter pairs and the sequence is one jump going forwards in the alphabet. When working out the sequence you look at the last letter of the first letter pair and work out the number of jumps to the first letter of the next letter pair. So one jump from GH is IJ. Great!
• Question 2

Here are two letter sequences that both follow the same pattern:

EF is to IJ as RS is to ______ ?

 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
VW
EDDIE SAYS
How did you get on? Each sequence follows the order of the alphabet going forwards, with three jumps each time. So three jumps after RS is VW.
• Question 3

Here are two letter sequences that both follow the same pattern:

MN is to XY  as GH is to ______ ?

 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
RS
EDDIE SAYS
Getting the hang of it? Both sequences follows the order of the alphabet going forwards, with ten jumps each time. So ten jumps from GH is RS.
• Question 4

Here are two letter sequences that both follow the same pattern:

VW is to AB as IJ is to ______ ?

 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
NO
EDDIE SAYS
Fantastic effort! Both sequences follow the order of the alphabet going forwards, with four jumps each time. Four jumps from IJ is NO.
Remember that you start back at the beginning of the alphabet when following a forwards sequences that has reached the end of the alphabet.
• Question 5

Here are two letter sequences that both follow the same pattern:

WX is to GH as UV is to ______ ?

 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
EF
EDDIE SAYS
Both sequences follow the order of the alphabet going forwards, with nine jumps each time. Nine jumps from UV is EF. Good work detective, you're already halfway through this activity!
• Question 6

Here are two letter sequences that both follow the same pattern:

DC is to BA as HG is to ______ ?

 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
FE
EDDIE SAYS
Did you work this one out? This time both sequences go backwards in the alphabet. There is one jump each time. So one jump back from HG is FE.
• Question 7

Here are two letter sequences that both follow the same pattern:

MN is to YZ as PQ is to ______ ?

 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
BC
EDDIE SAYS
Both sequences follow the order of the alphabet going forwards, with eleven jumps each time. So eleven jumps from PQ is BC. Super!
• Question 8

Here are two letter sequences that both follow the same pattern:

NM is to KJ as RQ is to ______ ?

 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
ON
EDDIE SAYS
Both sequences follow the order of the alphabet going backwards, with two jumps each time. So two jumps back from RQ is ON. Good work, detective!
• Question 9

Here are two letter sequences that both follow the same pattern:

WV is to QP as LK is to ______ ?

 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
FE
EDDIE SAYS
This sequence follows the order of the alphabet going backwards, with five jumps each time. So five jumps back from LK is FE.
Let's zoom onto the final question!
• Question 10

Here are two letter sequences that both follow the same pattern:

OP is to CD as TU is to ______ ?

 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
HI
EDDIE SAYS
Both sequences follow the order of the alphabet going forwards, with thirteen jumps each time. So thirteen jumps from TU is HI.
What could be better? You've located all the letters! Hooray!
