Question

Based on the English alphabetical order, three of the following four 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.)

The correct answer is
JMP

Alphabetical Order Patterns

The task is to identify the letter group that deviates from a common pattern established by the other three groups, based on English alphabetical sequence. The pattern is not related to vowel/consonant count or position.

Letter Group Analysis

We analyze the difference in positions between consecutive letters in each group using their respective place in the English alphabet (A=1, B=2, ... Z=26).

NQU Group Details

N is the 14th letter.
Q is the 17th letter (Position difference: $17 - 14 = 3$).
U is the 21st letter (Position difference: $21 - 17 = 4$).
The pattern is +3, +4.

DGK Group Details

D is the 4th letter.
G is the 7th letter (Position difference: $7 - 4 = 3$).
K is the 11th letter (Position difference: $11 - 7 = 4$).
The pattern is +3, +4.

PSW Group Details

P is the 16th letter.
S is the 19th letter (Position difference: $19 - 16 = 3$).
W is the 23rd letter (Position difference: $23 - 19 = 4$).
The pattern is +3, +4.

JMP Group Details

J is the 10th letter.
M is the 13th letter (Position difference: $13 - 10 = 3$).
P is the 16th letter (Position difference: $16 - 13 = 3$).
The pattern is +3, +3.

Odd Group Identification

Groups NQU, DGK, and PSW share a consistent pattern: the position increases by 3, then by 4.

Group JMP exhibits a different pattern, increasing by 3 and then by 3.

Therefore, JMP is the letter group that does not belong to the established pattern.
