Answer:

1st term = -5

4th term = -17

8th term = -33

Step-by-step explanation:

1st term = -2 x (2 x 1) -1

             = -2 x 2 - 1

             = -4 - 1 = - 5

4th term = -2 x (2 x 2) -1

              = -2 x 4 - 1

              = -8 - 1 = - 9

8th term = -2 x (2 x 8) - 1

              = -2 x 16 - 1

              = -32 - 1 = - 33
