Which letter will replace the question mark (?) in the following series?
K, M, Q, ?, E
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → W
Write each letter as its place in the alphabet and look at the gaps between neighbours; after Z the count continues from A.
K (11) to M (13) is 2 places, and M (13) to Q (17) is 4 places, so the gaps grow by 2
The next gap is 6: \(17+6=23\), that is W
The gap after that is 8: W to E is X, Y, Z, A, B, C, D, E, 8 places, which matches the last letter
So the missing letter is W.
