First, the three numbers must be added:20 + 22 + 23 = 65Then the sum must be divided by three, because that is how many numbers there are:65 / 3 = 21 1/3The average of 20, 22, and 23 is 21 1/3.
All the numbers are composite except the ones in bold: 18 19 20 21 22 23 24 25.
20, 21, 22 and 23.
The prime number is 24
21+1=22 23-1=22 11x2=22 20+2=22 24-2=22, etc.
The Median is 23.5.
23
22
The median is 19.
I'm guessing you mean the median. The median is when you put all the numbers given in a set in order, for example: 20, 21, 22, 23, 24. The median is the number in the middle of the set, which would be 22 in this example. If you have two numbers in the middle, find the average of the two numbers, and that's your median!
22
20 + [(21+23)/22]2 = 20 + [44/22]2 = 20 + 22 = 20 + 4 = 24
