Question

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.

Answer 1

x=-18 or x=67

Explanation:

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)
