Their sum is 9, so the sum of the other 3 numbers must be 26. \n" ); document.write( "Again since we want to find the largest possible value for the largest number, the first two of the three numbers larger than or equal to 6 should be as small as possible. Since the unique mode is 1 and there are 3 of them, we can only have one more 6. \n" ); document.write( "So the first two numbers after the median are 6 and 7. The sum of the first 6 numbers is then 1+1+1+6+6+7=22, so the largest possible value for the largest number in the set is 35-22 = 13. \n" ); document.write( " |
