Answer:

Given A.P. is -40, -15, 10, 35,....

                    Here                  a1 = - 40

                    But                    a2 = a1 + d

                                       - 15 = - 40 + d                                           

                    or                      d = - 15 + 40 = 25

                                      

                                              =      - 40 + 9 x 25

                                              =      - 40 + 225 = 185
