Find the missing term in the alphanumeric series:

K3Y, L6X, I10W, ? , G21U, P28T

N15V

V15N

M15V

N14V

✅ Correct Option: 1

The numbers are $3, 6, 10, ?, 21, 28$ with differences $3, 4, 5, 6, 7$ , so the missing number is $10+5=15$ .

The last letters run backwards: Y, X, W, V, U, T, giving V.

The first letters K(11), L(12), I(9), ?, G(7), P(16) change by $+1, -3, +5, -7, +9$ , so $9+5=14=$ N.

Hence N15V.
