Which group of letters is the odd one out?
TVY is the odd one out. In ACE, HJL and MOQ each letter is exactly two places after the previous one. In TVY, T to V is two places but V to Y is three places, so the pattern is broken.
- AACE
- BHJL
- CMOQ
- DTVYCorrect
Explanation
ACE (1,3,5), HJL (8,10,12) and MOQ (13,15,17) each have a gap of 2 between consecutive letters. TVY has positions 20, 22, 25, so the gaps are 2 and 3. Hence TVY breaks the pattern.
