Differences between              Difference between             Difference between

numbers in sequence             first differences                    second differences

17 - 7 = 10

30 - 17 = 13                                          3      

51 - 30 = 21                                          8                                                   5

85 - 51 = 34                                         13                                                  5

137 - 85 = 52                                       18                                                  5

212 - 137 = 75                                      23                                                 5

                          75 + 28 = 103

212 + 103 = 315                                  28                                                 5

                         103 + 33 = 136

315 + 136 = 451                                   33                                                5
