Video Summary

The problem involves determining the median of five numbers given specific mean conditions. The mean of all five numbers is 24, and the mean of the three smallest numbers is 9, while the mean of the three largest numbers is 28. By setting equations based on these conditions and manipulating the sums and differences of equations, the value of the third number, which represents the median when the numbers are ordered, is found to be 21. Thus, the median of the five numbers is 21.
