The possible positive number that results to 6 is 3,2,1 sice when we add that three we will get 6 as the average.. and the largest number will be 3 since it is the highiest number...

MMMM actually the answer is16 is just that I don't know the solution. :)

Let x be the smallest number
[x+(x+1)+(x+2)]/3 = 6
x+x+1+x+2=18
3x+3=18
3x=18-3
3x=15
x=5

so the three numbers are 5,6 and 7. the largest possible number is 7 :)
MMMM guys actually the answer is16 is just that I don't know the solution. :)
then the three numbers is 1,1,16. I thought it has to be consecutive hehe. 1+1+16=18 average is still 6 ;3
