What is the median number for the numbers 4, 8, 10, 5, 9
Ipatiy [6.2K]
The median number means the middle number. Before finding the middle number, you must line up the numbers from decreasing to increasing size:

4, 5, 8, 9, 10

Then, simply find the number in the middle. Since there are five numbers in this list, the middle number will be the third one: 8.
