How to find the missing number
The range is calculated as the difference between the maximum and minimum values.
R = Max - Min
Given the set of numbers:
7, 4, 5, 6, 4, ?
Let the missing number be x. We find possible numbers using two condition
- 1. When the maximum is not 7
- 2. When the minimum value is not 4
When the maximum is not 7
Range = Max - Min
6 = x - 4
x = 10
When the minimum value is not 4
6 = 7 - x
x = 7 - 6
x = 1
