Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
MA, NZ, OY, PX, ?
Answer & explanation
Correct answer: option 2
Explanation:
MA, NZ, OY, PX, ?
The logic followed here is :
M → (+1) → N → (+1) → O → (+1) → P → (+1) → Q
A → (-1) → Z → (-1) → Y → (-1) → X → (-1) → W
So, the letter-cluster that replaces the (?) to complete the series is "QW"
