The 7th term is 1.

Step-by-step explanation:

Given : In a G.P. 729, 243, 81,…

To find : The value of $t_7$ ?

Solution :

In a G.P. 729, 243, 81,…

The first term is a=729

The common ratio is $r=\frac{243}{729}=\frac{1}{3}$

The 7th term of a G.p is given by,

$t_7=ar^6$

Substitute the values,

$t_7=(729)(\frac{1}{3})^6$

$t_7=729\times \frac{1}{729}$

$t_7=1$

Therefore, the 7th term is 1.
