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.
The first five prime numbers are 2, 3, 5, 7, and 11. I don't know what you mean by "of 28".
The first five two-digit prime numbers are 11, 13, 17, 19, and 23.
To find the sum of 8 numbers when the mean is 23, you can use the formula: sum = mean × number of values. In this case, the sum would be 23 × 8, which equals 184. Therefore, the sum of the 8 numbers is 184.

the mean of four numbers is 25 and three of the numbers are 17 23 and 25 what is the fourth number?
15 17 19 21 23.
The numbers are 21, 22, 23, 24, and 25.
The first five two-digit prime numbers are 11, 13, 17, 19, and 23.
The first five prime numbers above 10 are: 11, 13, 17, 19, 23.
To find the sum of 8 numbers when the mean is 23, you can use the formula: sum = mean × number of values. In this case, the sum would be 23 × 8, which equals 184. Therefore, the sum of the 8 numbers is 184.

They are: 21 23 25 27 and 29 which makes five of them
To calculate the mean you add all of the numbers together, and then divide by how many numbers were added. In this case, the mean is 21.
To calculate the mean of the numbers 23, 78, 45, and 22, first add them together: 23 + 78 + 45 + 22 = 168. Then, divide the total by the number of values, which is 4: 168 ÷ 4 = 42. Therefore, the mean of the numbers is 42.
