#### Question

Find the third term from the end of the G.P.

2/27, 2/9, 2/3,.........162

#### Solution

Given G.P. : 2/27, 2/9, 2/3,....,162
Here,
Common ratio, r =(2/9)/(2/27)=3

Last term, l = 162

∴ 3rd term from an end =1/"r"^2=162/(3)^2=162/9=18

Is there an error in this question or solution?
