In the following series, only one letter-cluster is incorrect. Select the incorrect letter-cluster.
YCG IMQ SVZ CGK MQU
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. SVZ.
Logic: 1st letter + 4 = 2nd letter; 2nd letter + 4 = 3rd letter
SVZ → S + 3 = V; V + 4 = Z
MQU → M + 4 = Q; Q + 4 = U
CGK → C + 4 = G; G + 4 = K
IMQ → I + 4 = M; M + 4 = Q
So, SVZ is the incorrect letter-cluster.
