Explanation:

Sure, let’s break it down:

- Option 1: HLOP

- Each letter is 3 steps ahead of the previous one in the alphabet. H (8), L (12), O (15), P (16): H to L (+4), L to O (+3), O to P (+1). Not a fixed pattern.

- Option 2: FHJL

- F (6), H (8), J (10), L (12). You’ve got a clear pattern: add 2 each time. F+2=H, H+2=J, J+2=L.

- Option 3: AEHI

- A (1), E (5), H (8), I (9). The jump is +4, +3, +1. So, no regular pattern of steps.

- Option 4: QUXY

- Q (17), U (21), X (24), Y (25). Jumps: +4, +3, +1, same as HLOP and AEHI.

What this really means is, FHJL is the only sequence with equal jumps (+2 throughout). The other three have a +4, +3, +1 jump pattern.

So the odd one out is:

Option 2: FHJL
