Answer:

a2=2        and a7=22

                       a+d=2-----------1

                       a+6d=22-------2

                          -5d=-20

                              d=4

substitute in equation 1 =a+d=2

                                          a=-2

a35=a+34d

      =-2+34[4]

       =-2+136=134

       =
