Well, isn't that a happy little question! To find five numbers with a mean of 9, we can simply choose numbers that add up to 45 (5 numbers multiplied by the mean of 9). For example, we could have 6, 7, 8, 10, and 14. Remember, in the world of numbers, there are no mistakes, just happy little accidents!

Let assume we are only considering whole numbers. So we have the series 9,9,11,x,y which must sum to 12*5 or 60 given the mean is 12. x and y can not be equal and they must be greater than 11. So x + y = 60- 9-9-11 = 60 - 29 = 31. So, x = 15, and y = 16.
