Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3. i.e. XKVW.
The series follows this pattern:
U + 1 = V; V + 1 = W; W + 1 = X; X + 1 = Y
Q - 2 = O; O - 2 = M; M - 2 = K; K - 2 = I
M + 3 = P; P + 3 = S; S + 3 = V; V + 3 = Y
I - 4 = E; E - 4 = A; A - 4 = W; W - 4 = S
