Consider the following 8 numbers, where one labelled x is unknown.
24, 4, 1 ,x, 39, 5 ,37, 48.
Given that the range of numbers is 66, work out two values of x.
you can either make it so 48 remains the largest number and so take 66 from 48 (=-18) or you can leave one as the smallest number and add 66 to one(=67)
