Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete? MHL21 OJN29 QLP37 SNR45 ?
UPT53
Take the first letters: M, O, Q, S, ? Each advances +2: M→O→Q→S→U. So the next first letter is U.
Take the second letters: H, J, L, N, ? Each advances +2: H→J→L→N→P. So the next second letter is P.
Take the third letters: L, N, P, R, ? Each advances +2: L→N→P→R→T. So the next third letter is T.
The numbers run 21, 29, 37, 45, each rising by 8, so the next number is 45 + 8 = 53.
Combining gives UPT53.
Hence, the missing cluster is UPT53.
