Three of the following four letter-clusters are alike in a certain way and thus form a group. Which is the one that does NOT belong to that group?
(Note: The odd one out is not based on the number of consonants/vowels or their position in the letter cluster.)
1) EFINU
2) BCFKR
3) JKNSZ
4) HIMQX
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. HIMQX.
Logic: 1st letter + 1 = 2nd letter; 2nd letter + 3 = 3rd letter; 3rd letter + 5 = 4th letter; 4th letter + 7 = 5th letter
Except HIMQX, all follow the logic.
