and many, many other combinations. Any 5 numbers that add up to 100 have an average of 20.

18, 19, 20, 21, 22 average out to 20. if we can't use 20, steal 3 from it, making it 17, and give the 3 to the 22, making it 25. you get

17, 18, 19, 21, 25.

or steal 1, or 5, or whatever. if the 5 numbers have an average of 20, all that's needed is that they have a total of 100.

3, 7, 10, 30, 50
9, 11, 15, 25, 40

Both sets of these numbers average out to 20. The key is to find 5 numbers that add up to 100, since 100/5 is 20.

Hope this helps!

any 5 numbers that add up to 100 will average out to be 20, trust me.
Ex. 19, 18, 17, 16, 30

You take any 5 numbers that add up to 100, that way when you divide by 5 to get the average, you're answer will be 20.

ex. 7,15, 19, 28, 31
7+15+19+28+31 = 100
100/5 = 20
Therefore, the average of those 5 numbers is 20.

Hope that helps!

30, 40, 10, 12, 8 = average of 20

5 x 4 = 20
5 x 2 x 2 = 20
5 x 5 - 5 = 20
5 - 4 x 10 x 2 = 20
5 + 5 x 2 = 20

oh that not using 20 makes it harder....
18,19,21,21,21
-X+2, -X+4, X-3, X-2, X-1 where X > 20

There are many sets of numbers that will average to 20...
