An = 4x-3
Put n = 1                                     Put n = 2
A1 = 4(1)-3                                  A2 = 4(2)-3
A1 = 4-3                                       A2 = 8-3
A1 = 1                                          A2 = 5

Now Find the Common Difference
          D = A2-A1
          D = 5-1
          D = 4
