12 : 432

13 : 506

8 : 192

7 : 147

- Let's look at the given pairs:

- 12 : 432

- Multiply 12 by 12 to get 144, and then by 3 to get 432.

- 13 : 506

- Multiply 13 by 13 to get 169, and then by 3 to get 507, not 506.

- 8 : 192

- Multiply 8 by 8 to get 64, and then by 3 to get 192.

- 7 : 147

- Multiply 7 by 7 to get 49, and then by 3 to get 147.

- In all pairs except 13 : 506, the number pairs follow the pattern: a number squared, then multiplied by 3, equals the second number.

- Hence, the pair 13 : 506 is different.
