Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
DJRZ, HDZP, LXHF, PRPV, ?
Answer & explanation
Correct answer: option 4

Explanation:
DJRZ, HDZP, LXHF, PRPV, ?
The logic followed here is :
D → (+4) → H → (+4) → L → (+4) → P → (+4) → T
J → (-6) → D → (-6) → X → (-6) → R → (-6) → L
R → (+8) → Z → (+8) → H → (+8) → P → (+8) → X
Z → (-10) → P → (-10) → F → (-10) → V → (-10) → L
So, the letter-cluster that replaces the (?) to complete the series is "JXWE"
