Three of the following four letter groups are alike in a certain way. Choose the one that does not belong to the group.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → HEBY
Write each letter's place in the alphabet (A = 1, …, Z = 26) and find the backward jumps; before A the count goes on from Z.
Option (1) PLHD — P (16), L (12), H (8), D (4): jumps −4, −4, −4.
Option (2) FBXT — F (6), B (2), then 4 places back is X (2 − 4 + 26 = 24), then T (20): jumps −4, −4, −4.
Option (3) HEBY — H (8), E (5), B (2), then 3 places back is Y (2 − 3 + 26 = 25): jumps −3, −3, −3.
Option (4) VRNJ — V (22), R (18), N (14), J (10): jumps −4, −4, −4.
Three groups move 4 letters back at every step; HEBY moves 3 letters back, so HEBY is the odd one out.
