The mean of that set of numbers is 6. I don't think there is such a set of numbers, though I may be wrong.
OK, so I found a set that fits that desciption:
3.5, 7, 7, 10.5
There are an infinite amount of sets that fit that desciption, however, since you can add a seven in the middle any number of times, so
3.5, 7, 7, 7, 10.5
is also a valid set
3.5, 7, 7, 10.5

I think natural numbers need to be whole numbers. The set in the teaser now does satisfy all of the requirements.
4,5,7,7,7,8,11
4,5,6,7,7,9,11
3,5,7,7,7,10,10
3,6,7,7,7,9,10
3,7,7,7,7,8,10
2,7,7,7,8,9,9
are other answers.
