Which letter will replace the question mark (?) in the following series?
K, Q, V, ?, C, E, F
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Z
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 Q (17) is 6 places ahead, and Q (17) to V (22) is 5 places ahead, so the gaps fall by 1 each time
The next gap is 4: \(22+4=26\), that is Z
Z to C is 3 places (A, B, C), C (3) to E (5) is 2 places and E (5) to F (6) is 1 place, so the later letters fit the same rule
So the missing letter is Z.
