Question

Consider the following 8 numbers, where one labelled x is unknown.

11, 1, 34, x, 41, 10, 47, 2

Given that the range of the numbers is 67,

work out 2 values of x.

Answer 1

x=-20 or x=68

Explanation:

you can either make it so 47 remains the largest number and so take 67 from 47 (=-20) or you can leave 1 as the smallest number and add 67 to 1 (=68)
