Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
KRA, IQZ, ?, EOX, CNW
Answer & explanation
Correct answer: option 2
Explanation:
KRA, IQZ, ?, EOX, CNW
The logic followed here is :
K → (+2) → I → (+2) → G → (+2) → E → (+2) → C
R → (-1) → Q → (-1) → P → (-1) → O → (-1) → N
A → (-1) → Z → (-1) → Y → (-1) → X → (-1) → W
So, the letter-cluster that replaces the (?) to complete the series is "GPA"
