Which of the following letter clusters will replace the question mark (?) and complete the following letter-cluster series?
EU, CS, YQ, SO,?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. KM.
Given series: EU, CS, YQ, SO,?
The series follows this pattern:
EU, CS
E - 2 = C
U - 2 = S
CS, YQ
C - 4 = Y
S - 2 = Q
YQ, SO
Y - 6 = 19
Q - 2 = O
SO,?
S - 8 = K
O - 2 = M
So, the next term in the series is KM.
