A list of 5 positive integers has the following properties: the only integer in the list that occurs more than once is 8; the median of the numbers in the list is 9; and the average of the numbers in the list is 10. What is the largest possible integer that could appear in the list?

    Its been awhile, but does median mean the middle number, Ex: (1,4,9) median=4?

    and does the list have to go from smallest to largest?

    I think I am right; so lets try this: (8,8,9,x,y) and (8+8+9+x+y)/5 = 10 25+x+y= 50 x+y=25 10 is the next smallest interger; and 10 + 15 = 25. So I would say that 15 is the largest interger that could apper in the list.
