12 : 156

18 : 342

17 : 307

14 : 210

- Let's look at the pattern in each pair. Is there a simple operation that relates the two numbers?

- Option 1: 12 : 156

- The operation is \(12 \times 13 = 156\).

- Option 2: 18 : 342

- Here, \(18 \times 19 = 342\).

- Option 3: 17 : 307

- This pair shows \(17 \times 18 = 306\). It should be 306 to match the pattern.

- Option 4: 14 : 210

- This follows \(14 \times 15 = 210\).

- Answer: The patterns in Option 1, 2, and 4 show that each first number is multiplied by its successor to get the second number.

- Option 3 is different because the pattern isn't followed exactly. The product is off by 1.

- Correct Answer: Option 3, 17 : 307
