129

The series is a geometric progression.

The first term (a) = -3

Common ration (r) = 6/-3

                          = -2

The formula for getting the sum of a geometric progression is

Sum = a(rⁿ - 1)/(r - 1)

          = -3(-2⁷ - 1)/(-2 - 1)

          = -3(-128-1)/-3

            = (-3 × -129)/-3

              = -129
