Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
THME, WKJB, ZNGY, CQDV, ?
Answer & explanation
Correct answer: option 4
Explanation:
THME, WKJB, ZNGY, CQDV, ?
The logic followed here is :
T → (+3) → W → (+3) → Z → (+3) → C → (+3) → F
H → (+3) → K → (+3) → N → (+3) → Q → (+3) → T
M → (-3) → J → (-3) → G → (-3) → D → (-3) → A
E → (-3) → B → (-3) → Y → (-3) → V → (-3) → S
So, the letter-cluster that replaces the (?) to complete the series is "FTAS"
