Rebecca has the following data:

If the range is 6, which number could u be?

The range is the difference between the greatest number and the least number.

Try u = 13.

Arrange the numbers from least to greatest.

Subtract the least number from the greatest number.

15 − 12 = 3

When u = 13, the range is 3.

Try u = 18.

Arrange the numbers from least to greatest.

Subtract the least number from the greatest number.

18 − 12 = 6

When u = 18, the range is 6.

The range is 6, so u = 18.
