The pattern followed here is:

Logic: First term × 3 + 3 = Second term

Now we consider the given options:

Option 1) 7 – 24

× 3 + 3 = 24

21 + 3 = 24

24 = 24

Option 2) 13 – 42

13 × 3 + 3 = 42

39 + 3 = 42

42 = 42

Option 3) 11 – 37

11 × 3 + 3 = 37

33 + 3 = 37

36 ≠ 37

Option 4) 5 – 18

5 × 3 + 3 = 18

15 + 3 = 18

18 = 18

So, 11 – 37 is an odd one.

Hence, the correct answer is "Option 3".
