There are infinitely many answers. Curiously, perhaps, one of them is 1,1,1,1 and 111.

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
Since there are five numbers in that group, the mean (average) of the group is 1/5 of their sum.
if you mean what three prime numbers add up to a prime number then the answer is : 5 + 7 + 11 = 23

22.2. To calculate the mean, total the numbers, and then divide by the number of figures added. So, the total is 111. Divide 111 by 5 = 22.2
