The average of seven different whole numbers is 7. what is the largest possible value of any of these numbers?

Whole numbers are numbers that are not negative. I.e. {0, 1, 2, 3...} as such, to find the largest value a number in a set of seven whole numbers can be, we must assume that six of the seven numbers are the smallest they can be, as in 0.
Remembering how to find an average, , where n is the number of terms, in this case 7, we can find the highest possible number.
To do this, we set through to 0. This gives us .
Solving, we get that or that the largest possible value of any of the numbers is 49.
