Select the letter-cluster from among the given options that can replace the question mark (?) in the following series. RAT, UEY, XID, ?, DQN
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e AMI
Given series: RAT, UEY, XID, ?, DQN
The logic used here is:
R + 3 = U, A + 4 = E, T + 5 = Y
U + 3 = X, E + 4 = I, Y + 5 + D
Similarly, X + 3 = A, I + 4 = M, D + 5 = I
Hence, option 1 is the correct option.
