Step-by-step explanation:
![a_{1} = 8\\a_{9} = 360 = a_{1} \cdot r^9 = 8 \cdot r^9\\r = \sqrt[9]{\frac{360}{9} } \cong 1.53](https://tex.z-dn.net/?f=a_%7B1%7D%20%3D%208%5C%5Ca_%7B9%7D%20%3D%20360%20%3D%20a_%7B1%7D%20%5Ccdot%20r%5E9%20%3D%208%20%5Ccdot%20r%5E9%5C%5Cr%20%3D%20%5Csqrt%5B9%5D%7B%5Cfrac%7B360%7D%7B9%7D%20%7D%20%20%5Ccong%201.53)
By the formula of a geometric series:

I’m pretty sutures it’s 0.01396 but I might be wrong
