22 : 490

25 : 631

21 : 447

30 : 908

Let's analyze each option:

- Option 1: 22 : 490

If you multiply 22 by 22 and then add 6 (22x22 + 6 = 484 + 6 = 490), it matches.

- Option 2: 25 : 631

25x25 + 6 = 625 + 6 = 631, matches the pattern.

- Option 3: 21 : 447

21x21 + 6 = 441 + 6 = 447, follows the same pattern.

- Option 4: 30 : 908

30x30 + 6 = 900 + 6 = 906, NOT 908. So, this does not fit the pattern.

Option 4: 30 : 908 is the odd one out.
