term is

   

and common ratio is

   

.
contexto.140

From the question it is given that,

a8 =

   

and r =

   

Then, by the formula

   

   

Now,

   

  1. In a GP., the third term is

       

    and

       

     term is

       

    . Find the

       

     term.

Solution:-

From the question it is given that,

   

Then, by the formula

   

   

   

 … [equation (i)]

Now,

   

   

   

… [equation (ii)]

By dividing equation (i) by equation (ii)

   

Now, substitute the value r in equation (i),

   

So,
