Question

Based on the English alphabetical order, three of the following four letter-cluster pairs are alike in a certain way and thus form a group. Which letter-cluster pair 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
TQ - KO

Alphabetical Order Letter Cluster Pairs

The task is to identify the letter-cluster pair that deviates from a pattern shared by the other three, based on alphabetical sequence.

Letter Pair Analysis

We evaluate each pair using the numerical positions of letters (A=1 to Z=26) and the difference between letters within each cluster.

PM - OL Pair Analysis

Positions:

  • P=16, M=13
  • O=15, L=12

Difference (PM): \(16 - 13 = 3\).

Difference (OL): \(15 - 12 = 3\).

Differences match (\(3=3\)).

TQ - KO Pair Analysis

Positions:

  • T=20, Q=17
  • K=11, O=15

Difference (TQ): \(20 - 17 = 3\).

Difference (KO): \(11 - 15 = -4\).

Differences do not match (\(3 \neq -4\)).

MJ - LI Pair Analysis

Positions:

  • M=13, J=10
  • L=12, I=9

Difference (MJ): \(13 - 10 = 3\).

Difference (LI): \(12 - 9 = 3\).

Differences match (\(3=3\)).

VS - UR Pair Analysis

Positions:

  • V=22, S=19
  • U=21, R=18

Difference (VS): \(22 - 19 = 3\).

Difference (UR): \(21 - 18 = 3\).

Differences match (\(3=3\)).

Odd Letter Pair Out

A consistent pattern exists where the numerical difference between letters in the first cluster equals the difference in the second cluster for pairs PM-OL, MJ-LI, and VS-UR.

The TQ - KO pair fails this pattern as the differences (\(3\) and \(-4\)) are unequal. Thus, TQ - KO is the odd one out.
