Some groups of letters are given, all of which except one, share a common similarity while one is different. Select the odd one.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → GHJL
Writing each letter’s place in the alphabet shows the gaps between the letters of each group:
Option (1) RTVX — 18, 20, 22, 24: each letter is 2 places after the one before.
Option (2) NPRT — 14, 16, 18, 20: gaps of 2, 2, 2.
Option (3) GHJL — 7, 8, 10, 12: the gaps are 1, 2, 2, so GHJL is the odd one out.
Option (4) ACEG — 1, 3, 5, 7: gaps of 2, 2, 2.
