Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
WUW, TSV, QQU, NOT, ?
Answer & explanation
Correct answer: option 1
Explanation:
WUW, TSV, QQU, NOT, ?
The logic followed here is :
W → (-3) → T → (-3) → Q → (-3) → N → (-3) → K
U → (-2) → S → (-2) → Q → (-2) → O → (-2) → M
W → (-1) → V → (-1) → U → (-1) → T → (-1) → S
So, the letter-cluster that replaces the (?) to complete the series is "KMS"
