12 : 432

13 : 506

8 : 192

7 : 147

Let’s break down each option.

- 12 : 432

If you multiply 12 × 12 × 3, you get 432. So that's (n × n × 3).

- 13 : 506

Try that same logic: 13 × 13 × 3 = 507. But here the pair is 506. That’s off by one.

- 8 : 192

8 × 8 × 3 = 192. Fits the pattern exactly.

- 7 : 147

7 × 7 × 3 = 147. Again, a perfect fit.

Here’s what this means: All the pairs except 13 : 506 use the “n × n × 3” rule and match perfectly. The odd one out is definitely option 2.

Option 2—13 : 506 is the different one.
