Question : Directions: Select the letter cluster from among the given options that can replace the question mark (?) in the following series.
MA, NZ, OY, PX, ?
Option 1: QV
Option 2: QW
Option 3: WQ
Option 4: QR
Correct Answer: QW
Solution :
Given:
MA, NZ, OY, PX, ?
Add 1 in the first letter and subtract 1 from the second letter, to obtain the required missing term in the series –
MA → M + 1 = N, A – 1 = Z → NZ
NZ → N + 1 = O, Z – 1 = Y → OY
OY → O + 1 = P, Y – 1 = X → PX
PX → P + 1 = Q, X – 1 = W → QW
So, the required missing term in the series is QW. Hence, the second option is correct.
