Explanation:

- In the given set (5, 60, 70):

- 5 multiplied by 12 equals 60.

- Adding 10 to 60 gives 70.

- In the set (9, 108, 126):

- 9 multiplied by 12 equals 108.

- Adding 18 to 108 gives 126.

Now, let's examine the options:

- Option 1: (7, 84, 98)

- 7 multiplied by 12 equals 84.

- Adding 14 to 84 gives 98.

- This set maintains the same rule.

- Option 2: (4, 48, 52)

- 4 multiplied by 12 equals 48.

- Adding 4 to 48 gives 52.

- The rule differs.

- Option 3: (6, 72, 74)

- 6 multiplied by 12 equals 72.

- Adding 2 to 72 gives 74.

- The rule differs.

- Option 4: (8, 84, 112)

- 8 multiplied by 12 equals 96, not 84.

- Adding to a wrong product differs from the rule.
