The logic followed here is:

Logic: (1st number ÷ 2) + 1st number = 2nd number.

Let's check one by one.

Option 1) 6:9

⇒ 6 ÷ 2 = 3 + 6 = 9.

Option 2) 7:73

⇒ 7 ÷ 2 = 3.5 + 7 = 10.5.

Here, doesn't follow the pattern.

Option 3) 18:27

⇒ 18 ÷ 2 = 9 + 18 = 27.

Option 4) 14:21

⇒ 14 ÷ 2 = 7 + 14 = 21.

Hence, the correct answer is "Option 2".
