Does anyone know how to find a range of a number? These are the numbers I have to find the range of.

7,7,5,4,1,9,8,8,8,5,2

Please help!!

The range is the possible values.

In this case 1 , 2 , 4 , 5 , 7 , 8 , 9
because it says nothing in your problem about other numbers between 1 and 9, such as 3, being allowed or any fractional numbers between being allowed.
