Series of Alphabets: Rules
Questions related to series of Alphabets can be asked based on certain rules:
Rule 1: Series can have forward counting numbers from A = 1, z = 26
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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26
(Left) ------------------------------------------------------------------------------------------ (Right)
This is English alphabetical order.
Rule 2: Series can have Reverse counting numbers from A=26, Z = 1
Z Y X W V U T S R Q P O N M L K J I H G F E D C B A
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

Series Examples
Series: B E I N T ? (Series of one letter)
(a) W (b) Y (c) A (d) C
Solution:
+3 +4 +5 +6
B → E → I → N → T
So,
Next number will be +7 after T i.e.
U V W X Y Z A
1 2 3 4 5 6 7
(Remember after Z,series continues again from A)
So, Answer is A
Series: AZ CX
FU JQ ? (Series of two letter)
(a) OL (b) MK (c) OK (d) ML
Solution:
First Letter
+2 +3 +4
A → C → F → J
So, Next letter will be J + 5 = K L M N O , So, next first letter is O.
Second Letter
- 2 - 3 - 4
Z → X → U → Q
So, Next letter will be Q - 5 = P O N M L , So, next first letter is L.
So the next term of the series will be OL. Answer is OL
