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 =![a_{1} r^{4}](https://tex.z-dn.net/?f=a_%7B1%7D%20r%5E%7B4%7D)
Here ![a_{1} = -2](https://tex.z-dn.net/?f=a_%7B1%7D%20%3D%20-2)
Plug in
in the fifth term and find the value of r.
-1/8 = -2![r^{4}](https://tex.z-dn.net/?f=r%5E%7B4%7D)
![r^{4} = \frac{-1/8}{-2}](https://tex.z-dn.net/?f=r%5E%7B4%7D%20%3D%20%5Cfrac%7B-1%2F8%7D%7B-2%7D)
![r^{4} = \frac{1}{16}](https://tex.z-dn.net/?f=r%5E%7B4%7D%20%3D%20%5Cfrac%7B1%7D%7B16%7D)
Taking 4th root, we get
r = ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
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

Answer:
x= -10
Step-by-step explanation:
Divide both sides by the numeric factor on the left side, then solve.
x = − 10
