Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
MCN, NCO, OCP, PCQ, ?
Answer & explanation
Correct answer: option 1
Explanation:
MCN, NCO, OCP, PCQ, ?
The logic followed here is :
M → (+1) → N → (+1) → O → (+1) → P → (+1) → Q
C → (0) → C → (0) → C → (0) → C → (0) → C
N → (+1) → O → (+1) → P → (+1) → Q → (+1) → R
So, the letter-cluster that replaces the (?) to complete the series is "QCR"
