Step 1: Arrange the numbers from least to greatest.

               GIVEN: 13, 6, 10, r

                              r = ?

                             Mode = 13  

            Least to greatest.  

                           6, 10, 13, (r =?)

Step 2: Find the missing number

            NOTE: The mode is the number that appears most often.

              From the definition

                          6 - 1 time

                         10 - 1 time

                         13 - 1 time

         This all numbers are repeating only one time. so we can find the mode based    

         on the r value.    


             If r = 13  

                          6, 10, 13, 13

           The number that appears most often is 13. When r = 13, the mode is 13.


           ( If you take r = 6 or 10, then 6 or 10 will become mode. but in the question

             they given the mode as 13, So I took r = 13)
