Which letter will come in place of the question mark (?) in the given series?
M, L, N, M, O, N, ?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → P
Write each letter with its place in the alphabet and look at the change from one letter to the next.
M (13), L (12), N (14), M (13), O (15), N (14)
The changes are \(-1, +2, -1, +2, -1\): the series goes one back, two forward in turn
Next change \(+2\): N (14) \(+2=16\), which is P
The letters at the odd places, M, N, O, also continue to P.
