Select the letter-cluster that can replace the question mark (?) in the given letter-cluster series.
KOY, JPX, IQW, HRV, ?
Answer & explanation
Correct answer: option 2
Explanation:
KOY, JPX, IQW, HRV, ?
The logic followed here is :
K → (-1) → J → (-1) → I → (-1) → H → (-1) → G
O → (+1) → P → (+1) → Q → (+1) → R → (+1) → S
Y → (-1) → X → (-1) → W → (-1) → V → (-1) → U
So, the letter-cluster that replaces the (?) to complete the series is "GSU"
