I don't know this one sorry:(

Seems like it's multiplying by (-3) each time. 1*(-3) = -3. -3*(-3) = 9. 9*(-3) = -27. -27*(-3) = ?

Yes they are. The pattern is that each number is being multiplied by -3

anonymous · Answer

$\Large 1, -3, 9, -27= (-3)^0, (-3)^1 , (-3)^2 , (-3)^3 $
So,the next three terms of the sequence: 
            $\Large (-3)^4,(-3)^5,(-3)^6=81,-243,729$

The correct answer is C
