The answer would be B. -531,441.
There are 2 ways you can find this.
A. You can find this by starting with 3, and multiply -3 then multiply -3 to each product after that 11 times. Or...
B. Simply find 3 to the 12th power. Then add a negative since each even term (term 2, 4, 6, etc) are negative.
I hope this helps!
