Question

Find an equation for the relationship using that include exponents

Answer 1

`a_n= 2^(n-1)`

Explanation:

From the given table, the first term is

`a_1=1`

There is a common ratio of

`r = (2)/(1) = 2`

The formula is given by:

`a_n=a_1r^(n-1)`

We substitute the values to get:

`a_n=1 * 2^(n-1)`

This simplifies to:

`a_n= 2^(n-1)`
