Select the letter-cluster that can replace the question mark (?) in the given letter-cluster series.
YM, WO, UQ, ?, QU
Answer & explanation
Correct answer: option 2
Explanation:
YM, WO, UQ, ?, QU
The logic followed here is :
Y → (-2) → W → (-2) → U → (-2) → S → (-2) → Q
M → (+2) → O → (+2) → Q → (+2) → S → (+2) → U
So, the letter-cluster that replaces the (?) to complete the series is "SS"
