Answer:
1, 8, 9
Explanation:
total sum of 3 numbers, 6 * 3 = 18
since the median is 8 the second number should be 8.
it is now left with 2 numbers that total to 10
The third number should be 8 or higher, but it can't be 8 because all of the numbers are different. The third number should be 9 and the first number is going to be 1
