# Find the Alphabet Sequence Using Single Letter Pairs Moving Forwards or 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:

RS is to HI as JK is to __ ?

Use your detective skills to find the missing letter pair.

 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
ZA
EDDIE SAYS
First one done, how did you get on? Each sequence has letter pairs and the sequence is fifteen jumps forwards in the alphabet each time. So fifteen jumps from JK is ZA.
• Question 2

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

LK is to DC as FE is to __ ?

Use your detective skills to find the missing letter pair.

 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
YX
EDDIE SAYS
Each sequence follows the order of the alphabet going backwards six jumps. So six jumps back from FE is YX. Remember that if you are going backwards and reach the start of the alphabet, continue be going to the end of the alphabet. This is the opposite of what you would do if it was a forwards sequence, where you would start back at the beginning of the alphabet. Great!
• Question 3

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

VU is to ML as WV is to __ ?

Use your detective skills to find the missing letter pair.

 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
NM
EDDIE SAYS
Super effort detective! Both sequences follows the order of the alphabet going backwards, with eight jumps each time. So eight jumps back from WV is NM.
• Question 4

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

TS is to NM as DC is to __ ?

Use your detective skills to find the missing letter pair.

 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
XW
EDDIE SAYS
Both sequences follow the order of the alphabet going backwards, with five jumps each time. So five jumps back from DC is XW. Great!
• Question 5

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

ST is to FG as UV is to __ ?

Use your detective skills to find the missing letter pair.

 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
Sensational sequencing skills! Both sequences follow the order of the alphabet going forwards, with twelve jumps each time. So twelve jumps on from UV is HI.

HG is to XW as DC is to __ ?

Use your detective skills to find the missing letter pair.

 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
TS
EDDIE SAYS
Did you work this one out? Both the sequences follow the alphabet backwards, with nine jumps each time. So nine jumps back from DC is TS.
• Question 7

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

OP is to UV as XY is to __ ?

Use your detective skills to find the missing letter pair.

DE
EDDIE SAYS
Both sequences follow the order of the alphabet going forwards, with five jumps each time. So five jumps on from XY is DE. Lovely!
• Question 8

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

PQ is to KL 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
DE
EDDIE SAYS
Phew! There are an enormous twenty jumps in forwards in the alphabet for each sequence. So twenty jumps from IJ is DE.
• Question 9

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

RQ is to FE as JI is to __ ?

Use your detective skills to find the missing letter pair.

 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
XW

OP
EDDIE SAYS
Both sequences follow the order of the alphabet going forwards, with eleven jumps each time. So eleven jumps from CD is OP. Well done for completing your letter locating mission, hope to see you again soon!
