Step 1: Arrange the numbers from least to greatest.

              GIVEN: 15, 13, 10, 14, y


               Least to greatest: 10, 13, 14, 15

                                           y = ?

        If y = more than 13 then the median will be 14

        If y = less than 13 then the median will be 13

  

      So, assume any value of y less then 13 because the given median is 13

               y = 12, 11, 9,..........


          For example take  y = 9

                     9, 10, 13, 14, 15

                      n = 9 (odd)

          So the middle value if median

          The number in the middle is 13. When y = 9, the median is 13.
