# How do you write the explicit formula for the sequence 1, 1/3, 1/9 , 1/27…?

$\frac{1}{3} ^ n \text{ }$where $n = 0 , 1 , 2 , 3 , 4 , \ldots \ldots .$

#### Explanation:

Let me show you

$\frac{1}{3} ^ 0 , \frac{1}{3} ^ 1 , \frac{1}{3} ^ 2 , \frac{1}{3} ^ 3 , \frac{1}{3} ^ 4 , , , , \frac{1}{3} ^ n$

this is equivalent t0

$\frac{1}{1} , \frac{1}{3} , \frac{1}{9} , \frac{1}{27} , \frac{1}{81} , \ldots . .$

God bless....I hope the explanation is useful.
