Choose the missing term in the series from the options given below:
J2AZ, M4BY, L6CX, O8DW, ?, Q12FU
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → N10EV
Each term has four parts, and each part follows its own pattern through the series.
First letters J, M, L, O, ?, Q: the steps alternate +3, −1 (J +3 = M, M −1 = L, L +3 = O), so the next is O −1 = N (and N +3 = Q fits the last term)
Numbers 2, 4, 6, 8, ?, 12: even numbers, so the next is 10
Third letters A, B, C, D, ?, F: one letter on each time, so E
Last letters Z, Y, X, W, ?, U: one letter back each time, so V
