Explanation:

Let's analyze the number pairs:

- The given set: (98, 107, 125)

- Difference: 107 - 98 = 9, 125 - 107 = 18

- 18 is twice 9 (9 × 2 = 18)

- Let's check the options:

- Option 1: (122, 131, 149)

- 131 - 122 = 9, 149 - 131 = 18

- Same relationship as the given set

- Option 2: (319, 328, 346)

- 328 - 319 = 9, 346 - 328 = 18

- Same relationship as the given set

- Option 3: (73, 82, 99)

- 82 - 73 = 9, 99 - 82 = 17

- Second difference is NOT double the first (17 ? 18)

- This pair is different.

- Option 4: (29, 38, 56)

- 38 - 29 = 9, 56 - 38 = 18

- Same relationship as the given set

Correct Option:

Option 3: (73, 82, 99) does NOT share the same relationship.
