Math stumbler HELP ME !!!!!!!!!!!!!!!!!! I need the wifi code

first we have 8*6 as the total value of the set of number (no.)

and we have 8 as the medium of the set of no.,so the middle two no. is 8*2=16, as each of the set no. is unqiue, so the middle to number is 6 and 10, _ _ 6 10 _ _ and as each no is not greater than 13 , the greatest no. is 13, so we have _ _ 6 10 _ 13 by subtraction, we have 48-13-16=19, we can have 9 between 10 and 13 , then 10 leave , we can make the least number by subtracting 8 from 10 , so we get 2 finally, 

sorry one mistake  for my previous post, it should be 19-12 instead of 9 , so we have 12 in the middle of 10 and 13, and 7 is leave, so the least no can be on=btain by subtracting 5 from 7 so , the least no is still 2, the set of no is 2 5 6 10 12 13.
