Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
TOM, UMP, VKS, ?, XGY
Answer & explanation
Correct answer: option 2
Explanation:
TOM, UMP, VKS, ?, XGY
The logic followed here is :
T → (+1) → U → (+1) → V → (+1) → W → (+1) → X
O → (-2) → M → (--2) → K → (-2) → I → (-2) → G
M → (+3) → P → (+3) → S → (+3) → V → (+3) → Y
So, the letter-cluster that replaces the (?) to complete the series is "WIV"
