Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete? ICX 9, LFZ 16, OIB 25, RLD 36, ?
UOF 49
Track each of the three letter positions and the number separately.
First letters: I → L → O → R, each advancing by 3, so the next is U.
Second letters: C → F → I → L, each advancing by 3, so the next is O.
Third letters: X → Z → B → D, each advancing by 2, so the next is F.
Numbers: 9, 16, 25, 36 are \(3^2, 4^2, 5^2, 6^2\), so the next is \(7^2 = 49\).
Combining gives UOF 49.
Hence, the missing cluster is UOF 49.
