Question

Find an equation for the relationship using that include exponents

Answer 1

Answer:

$a_n= 2^{n-1}$

Step-by-step explanation:

From the given table, the first term is

$a_1=1$

There is a common ratio of

$r = \frac{2}{1} = 2$

The formula is given by:

$a_n=a_1r^{n-1}$

We substitute the values to get:

$a_n=1 \times 2^{n-1}$

This simplifies to:

$a_n= 2^{n-1}$
