Jackie has the following data:

If the range is 5, which number could v be?

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

Try v = 4.

Arrange the numbers from least to greatest.

Subtract the least number from the greatest number.

12 − 4 = 8

When v = 4, the range is 8.

Try v = 7.

Arrange the numbers from least to greatest.

Subtract the least number from the greatest number.

12 − 7 = 5

When v = 7, the range is 5.

The range is 5, so v = 7.
