Answer:

Step-by-step explanation:
<u><em>The complete question in the attached figure</em></u>
we know that
An equilateral triangle has three equal sides and three equal interior angles (the measure of each interior angle is 60 degrees)

Remember that
The <u><em>inscribed angle</em></u> is half that of the arc it comprises
so

Remember that
<u><em>Central angle</em></u> is the angle that has its vertex in the center of the circumference and the sides are radii of it
so
----> by central angle
Solution
Here the first term = -2
5th term = -1/8
Now we have to find the common ratio (r)
Fifth term A5 = -1/8
-1/8 =
Here 
Plug in
in the fifth term and find the value of r.
-1/8 = -2


Taking 4th root, we get
r = 
Now let's find the second term.
first term *r = -2 *1/2 = -1
2nd term = -1
3rd term = second term * 1/2 = -1 * 1/2 = -1/2
4th term = 3rd term *r = -1/2 *1/2 = -1/4
Thank you :)
The answer is x<20. Hope that helps.
42 is the answer your looking for.
