Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete? EIJ 33 GKL 27 IMN 21 KOP 15 ?
MQR 9
Look at each of the three letter positions separately across the clusters.
First letters: E, G, I, K, ... each increases by 2, so the next is M.
Second letters: I, K, M, O, ... each increases by 2, so the next is Q.
Third letters: J, L, N, P, ... each increases by 2, so the next is R.
So the letter part of the next cluster is MQR.
Numbers: 33, 27, 21, 15, ... each decreases by 6, so the next number is 15 − 6 = 9.
Hence, the cluster that completes the series is MQR 9.
