Find the missing group in the series: ACE, GIK, MOQ, ?
The missing group is SUW. The letters across all groups rise by two positions each time: A, C, E, G, I, K, M, O, Q continue as S, U, W. Therefore the fourth group, after MOQ, is SUW.
- ASUWCorrect
- BRTV
- CSTV
- DSUV
Explanation
Letters in the whole series follow every second letter: A, C, E, G, I, K, M, O, Q, then S, U, W. Each group starts where the previous one ended plus 2. So the missing group is SUW. SUV breaks the gap of two between U and V.
