Well, RANGE is the subtraction of the highest and lowest number in a series of numbers. So the range should be;
Highest number-lowest number
       The highest number in the list of numbers given is 88. And the lowest is 7. So;
88-7=81. So the range is 81. Hope i helped
In order to find the range of any set of numbers, you must look at the highest and lowest numbers.

In this case the highest is 88 and the lowest is 7.

To find the range you subtract these numbers.

So, 88 - 7 equals 81.

The range is 81!
