Question : Directions: Select the letter cluster that can replace the question mark (?) in the given letter–cluster series.
YM, WO, UQ, ?, QU
Option 1: TS
Option 2: SS
Option 3: ST
Option 4: RS
Correct Answer: SS
Solution :
Given:
YM, WO, UQ, ?, QU
In the above–given series, subtract 2 from the first letter and add 2 to the second letter of the previous term to obtain the next letter cluster.
YM→Y – 2 = W; M + 2 = O
WO→W – 2 = U; O + 2 = Q
UQ→U – 2 = S; Q + 2 = S
SS→S – 2 = Q; S + 2 = U
So, SS is the missing term in the series. Hence, the second option is correct.
