Choose the related letters from the given alternatives.
AF : BE :: ? : DH
- ACH
- BCG
- CDG
- DCI
Solution & Step-by-step Explanation
Let's observe the relationship between the pairs using letter positions:
A
+1
B
F
−1
E
So the pattern is +1 for the first letter and −1 for the second letter to get the next term.
Let the missing term be X
1
X
2
. Following the same rule to reach DH:
X
1
+1
D⟹X
1
=D−1=C
X
2
−1
H⟹X
2
=H+1=I
Therefore, the missing term is CI.
