Answer 1

The value of r in p/q form is 1/5

Step-by-step explanation:

If the first term of the GP is a and common ratio r

Then,

The nth term of GP is

$a_n=ar^{n-1}$

Given

$a_n=5(0.2)^{n-1}$

Comparing this to the general term, we get

$a=5$

$r=0.2$

or, $r=\frac{1}{5}$

Therefore, r in p/q form is 1/5
