Answer 2

Answer:

Given G. P. is 1/3, 1/9.1/27,......is 1/2187

Step-by-step explanation:

a=1/3.r=a2/a1=1/9/1/3=1/9×3/1=1/3

Let 1/2187 be the nth term of the G. P.,

Then, an=a.r^n-1= 1/2187

1/3×(1/3)^n-1=1/2187

(1/3)^n-1+1=(1/3)^7

(1/3)^n=(1/3)^7

n=7

2187=3×3×3×3×3×3×3

=3^7

1/2187=(1/3)^7

7th term of G. P. is 1/2187

Hence proved
