23*5 = 115
So pick any four numbers: integers, fractions, irrational numbers, whatever.
Add them together to give a sum S.
Let the 5th number be 115 - S
Then:
sum of all five numbers = (sum of the first four numbers) + (the fifth number)
= S + (115 - S) = 115
And the count of numbers = 5
So mean = Sum/Count = 115/5 = 23
