There are infinitely many sets.
{3,6,6,6,6,9} is one possibility.
the two numbers that have a mean of 10 and a range of 8 is 6 and 14
What four numbers have a range of 8, and has the same mean and mediun
3,5,6,7,9
{4,6,8}
6 + 14
12 and 8
8 and 4
3,6,7,9,13,16
(2, 2, 8)
2,5,7,10 would be one solution.
4 4 6 6 10
3, 4, 5, 6, 7, 8, and 9.
