I will presume that you are using the space of integers (as there are in infinite number of real or even rational numbers between 1 and 15).
There are 15 integers on the interval of [1,15] and we want to find all possible combinations of 6 numbers from this set.
We use a combination, 6C15= 15! / (6! * (15 - 6)!) = 15! / (6! * 9!)
If you do not have a calculator which does factorials or combinations, then you can do some cancellations to make the computation a little easier:
15! = 15 * 14 * 13 * 12 * 11 * 10 * 9!
so we can cancel the 9!, which leaves us with:
15 * 14 * 13 * 12 * 11 * 10 / 6!
This is still going to involve the multiplication and division of very large numbers, so I took the pansy route and just used a calculator and got:
5,005 different possible combinations.

How do you determine five numbers that have a mean of 23?
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
