HO22, JQ31, LS40, NU49, ? – Which of the following letter-number clusters will replace the question mark (?)

Let’s decode the sequence carefully:

We have:
HO22, JQ31, LS40, NU49, ?

Step 1: Look at the letters

• HO → JQ → LS → NU
• First letters: H → J → L → N
  • Sequence: +2 each time (H → J → L → N). Next will be P.
• Second letters: O → Q → S → U
  • Sequence: +2 each time (O → Q → S → U). Next will be W.

So the next letter pair is PW.

Step 2: Look at the numbers

• 22 → 31 → 40 → 49
• Each step increases by +9.

So next number = 49 + 9 = 58.

Answer

The missing cluster is:
PW58
