Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
PGF, QJK, RMP, SPU, ?
Answer & explanation
Correct answer: option 3
Explanation:
PGF, QJK, RMP, SPU, ?
The logic followed here is :
P → (+1) → Q → (+1) → R → (+1) → S → (+1) → T
G → (+3) → J → (+3) → M → (+3) → P → (+3) → S
F → (+5) → K → (+5) → P → (+5) → U → (+5) → Z
So, the letter-cluster that replaces the (?) to complete the series is "TSZ"
