Add them all together, then divide by the number of the amount of numbers. Say you wanted the mean of 2, 3, and 4. You would add 2, 3, and 4 then divide by 3, because there are 3 numbers.
To find the four numbers with a range of 6, a mean of 4, and a median of 3, we can start by setting up the median as the second and third numbers in ascending order. Since the median is 3, the second and third numbers are both 3. With a mean of 4, the sum of all four numbers is 4 * 4 = 16. To have a range of 6, the smallest number must be 3 - 3 = 0 and the largest number must be 3 + 6 = 9. Therefore, the four numbers are 0, 3, 3, and 9.
The range is 4.
3, 5, and 7. THIS BETTER NOT BE FOR YOUR HOMEWORK!
