Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
GCB, JHE, MMH, PRK, ?
Answer & explanation
Correct answer: option 3
Explanation:
GCB, JHE, MMH, PRK, ?
The logic followed here is :
G → (+3) → J → (+3) → M → (+3) → P → (+3) → S
C → (+3) → H → (+3) → M → (+3) → R → (+3) → W
B → (+3) → E → (+3) → H → (+3) → K → (+3) → N
So, the letter-cluster that replaces the (?) to complete the series is "SWN"
