Find the missing term in the alphanumeric series:
K3Y, L6X, I10W, ?, G21U, P28T
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → N15V
Each term has three parts, and each part follows its own pattern:
Numbers: 3, 6, 10, ?, 21, 28 rise by 3, 4, 5, 6, 7, so the missing number is \(10+5=15\)
Last letters: Y, X, W, ?, U, T go one letter back each time, so the missing letter is V
First letters run as two series in alternate terms:
1st, 3rd, 5th terms: K, I, G, going two letters back
2nd, 4th, 6th terms: L, ?, P, going two letters forward (L, N, P), so the missing letter is N
