Question

PLEASE HELP!!!!!!!!!!!!!!!!!!!! ASAP PLEASE!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

729

Explanation:

I have not done this in some time so the terms may be a bit unconventional, but they work. The key to this is multiplying by -3.

1*(-3) = -3

-3*(-3) = 9

And so on.

1, -3, 9, -27, 81, -243, 729
