r = - 
Step-by-step explanation:
The n th term of a GP is
= a₁ 
where a₁ is the first term and r the common ratio
Here a₁ = 18 and a₆ = - 
, then
18 
= - ( divide both sides by 18 )
= - 
( take the fifth root of both sides )
r = ![\sqrt[5]{-\frac{1}{243} }](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B-%5Cfrac%7B1%7D%7B243%7D%20%7D)
= -
