Three of the following letter-clusters are alike in some manner and one is different. Select the different one.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. WDXC.
The logic used here is: 1st letter - 5 = 2nd letter, 2nd letter - 4 = 3rd letter, 3rd letter - 3 = 4th letter
Option 1: WDXC: W - 5 = R, R - 4 = N, N - 3 = K: This does not follow the logic.
