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 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.)
RY-AS
OV-XP
NU-WO
DI-PW
DI-PW
Calculate the alphabetical positions and find the differences between the letters in each pair. Three pairs follow the same difference pattern, while one follows a different one.
Calculate the alphabetical positions and find the differences between the letters in each pair. Three pairs follow the same difference pattern, while one follows a different one.
Analyze Position Gaps (Right-Left)
Convert letters to numbers: R=18, Y=25; A=1, S=19; O=15, V=22; X=24, P=16; N=14, U=21; W=23, O=15; D=4, I=9; P=16, W=23.
Evaluate Difference Patterns
Pair A: (25-18) = +7, (19-1) = +18; Pair B: (22-15) = +7, (16-24) = -8; Pair C: (21-14) = +7, (15-23) = -8; Pair D: (9-4) = +5, (23-16) = +7.
Identify the Anomaly
Pairs B and C show a secondary relation/difference not found in D. Specifically, in B and C, the first cluster adds 7. In D, the first cluster adds 5. Thus, D is the odd one out.
A: Represents the sequence start/control; B: Follows the same secondary logic as C; C: Follows the logic pattern shared with B; D is the odd one out because the first cluster increment is +5, unlike others (+7).
D is correct because it is the only pair that does not follow the +7 increment pattern established by the other clusters.
In alphabetical analogy questions, always convert letters to their numerical positions (1-26) immediately to uncover arithmetic progressions that are not visible to the naked eye.
