Choose the word which is different from the sequence :
EH13, PR34, RU39, KN25
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → PR34
In each term the number is the sum of the alphabet positions of the two letters, and in three of the terms the second letter is 3 places after the first.
Option (1) EH13 — E (5) + H (8) = 13; E to H is +3.
Option (2) PR34 — P (16) + R (18) = 34; but P to R is only +2, so PR34 is the odd one out.
Option (3) RU39 — R (18) + U (21) = 39; R to U is +3.
Option (4) KN25 — K (11) + N (14) = 25; K to N is +3.
