Will give brainliest! please answer asap! question in pic!

an = a(r)^(n-1)

a is the 1st term

r is the common ratio

So, we have:

an=1(-4)^n-1

In the first box, put a "1", and the in the second box put a -4.

Let me know if this helps!

Step-by-step explanation:

The first term is -4 and the common ratio is;

The equation for this sequence is:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
