Question

Consider the following 8 numbers, where one labelled x is unknown. 42 , 6 , 28 , x , 11 , 19 , 37 , 50 Given that the range of the numbers is 52, work out 2 values of x .

Answer 1

-2 and 58

Explanation:

Range = highest number - lowest number

therefore from the observation,

x can be -2 because (50-(-2) = 50+2 = 52

x can also be 58 because (58-6) = 52
