The missing number is 18
22
The average is 23.
Average = sum(X)/n = 60/3 = 20
Since there is an even number of them, the median is the mean average of the middle two, namely [ 22 + 24 ] /2 = 23
94
The average of 18 and 22 is 18+22/2 = 20

The average is 22.
2:18-2:22
19.75 is the average.

18.
To find the average you need to add the two numbers together and divide by two. 18 + 22 = 40 40 / 2 = 20 The answer is 20.
It is: 14+15+22+21 = 72/4 => 18 which is the mean average
