Question

8 of 8

Consider the following 8 numbers, where one labelled X is unknown.
17, 18, 24, X, 44, 48, 42, 4
Given that the range of the numbers is 51,
work out 2 values of X.

Answer 1

55 and (-3)

Explanation:

The range is the difference between the smallest number and the biggest number.

If we take 4 as the smallest number, X would be the biggest number:

4 + 51 = 55

If we take 48 as the biggest number, X would be the smallest number:

48 - 51 = -3
