Three of the following four letter groups are alike in a certain way and one is different. Choose the odd one out.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → BEI
Write each letter's place in the alphabet (A = 1, B = 2, …, Z = 26) and find the jumps from one letter to the next.
Option (1) LOR — L (12), O (15), R (18): jumps +3, +3.
Option (2) HKN — H (8), K (11), N (14): jumps +3, +3.
Option (3) PSV — P (16), S (19), V (22): jumps +3, +3.
Option (4) BEI — B (2), E (5), I (9): jumps +3, +4.
Three groups move 3 letters at each step; BEI does not, so BEI is the odd one out.
