To circumscribe a circle to a given triangle implies constructing a circle outside the triangle, so that it touches the three vertices of the given triangle externally.

The step requires bisecting two sides of the triangle so as to locate the center of the circle. Then with the center and one of the edges, draw a complete circle. The circles should be outside the triangle and passing through its three vertices.

The construction is as shown in the attachment to this answer.

Answer:

The second choice

Step-by-step explanation:

So first we would plug in the first term which is 2 so we would get $an=2$ times $rn-1$ so next we would see that the common ration is -3 since every time the number is being multiplied by -3. so then our equation would be $an= 2$ times $-3n-1$ . Now we would just find the choice that matches and it would be the second choice.
