Explanation:

To find the relationship, let's examine the given set of numbers: 98 : 81 : 72.

- The numbers decrease by a certain pattern:

1. From 98 to 81, the difference is 17.

2. From 81 to 72, the difference is 9.

Now, let's analyze each option to find a similar pattern:

1. Option 1: 76 : 63 : 54

- 76 to 63, difference is 13.

- 63 to 54, difference is 9.

- The differences (13, 9) don't match the pattern (17, 9).

2. Option 2: 68 : 56 : 46

- 68 to 56, difference is 12.

- 56 to 46, difference is 10.

- The differences (12, 10) don't match the pattern (17, 9).

3. Option 3: 72 : 63 : 55

- 72 to 63, difference is 9.

- 63 to 55, difference is 8.

- The differences (9, 8) don't match the pattern (17, 9).

4. Option 4: 68 : 54 : 44

- 68 to 54, difference is 14.

- 54 to 44, difference is 10.

- The differences (14, 10) don't match the pattern (17, 9).
