Find the odd one out among the following letter groups: BD, FH, JL, NQ
NQ is the odd one out. In BD, FH and JL the second letter is two positions ahead of the first, but in NQ the second letter Q is three positions ahead of N, so the pattern is broken.
- ABD
- BFH
- CJL
- DNQCorrect
Explanation
In BD, FH and JL the second letter is exactly 2 places after the first (B-D, F-H, J-L). In NQ, Q is 3 places after N. So NQ breaks the pattern.
