Three of the following letter-clusters are alike in some manner and one is different. Select the one that is different
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. GTHS.
The logic used here is: 1st letter + 3 = 2nd letter, 2nd letter + 2 = 3rd letter, 3rd letter + 1 = 4th letter
Option 1: NQST: N + 3 = Q, Q + 2 = S, S + 1 = T: This follows the logic.
Option 2: GTHS: G + 3 = J, J + 2 = L, L + 1 = M: This does not follow the logic.
