Which letter cluster will replace the question mark (?) to complete the given series?
OSRE, QOXH, SKDK, ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. UGJN
Given series: OSRE, QOXH, SKDK, ?
The logic used here is:
O + 2 = Q, S - 4 = O, R + 6 = X, E + 3 = H
Q + 2 = S, O - 4 = K, X + 6 = D, H + 3 = K
Similarly, S + 2 = U, K - 4 = G, D + 6 = J, K + 3 = N
Hence, option 1 is the correct option.
