Answer 1

The logic follows here:

(1st number × 3) + 1 = 2nd number.

Now check all the options:

Option (1): 8 ∶ 25 → (8 × 3) + 1 = 24 + 1 = 25 = 2nd number

Option (2): 18 ∶ 73 → (18 × 3) + 1 = 54 + 1 = 55 ≠ 2nd number

Option (3): 22 ∶ 67 → (22 × 3) + 1 = 66 + 1 = 67 = 2nd number

Option (4): 15 ∶ 46 → (15 × 3) + 1 = 45 + 1 = 46 = 2nd number

Hence, "Option (2)" is different from others.
