Question

Find the 8th term in the Geometric Progression 1, 3, 9, ___

Answer 1

Step-by-step explanation:

a=1

r=3

nth term in go is a*r^(n-1)

1*3^(7)

2187

Answer 2

Answer:

8th term in the Geometric Progression = 2187

Step-by-step explanation:

Given Data :

Geometric Progression

1, 3 , 9

To find :

8th Term of the given Geometric Progression

1, 3 , 9

Here First Term = a  = 1

Common ratio = r = 3/1 = 9/3  = 3

nth term of a GP is given by  =  arⁿ⁻¹

putting a = 1  r = 3  n = 8

the 8th term would be  =  1 * 3⁸⁻¹  = 3⁷  =  2187

8th term in the Geometric Progression = 2187

1   3    9     27     81    243   729   2187
