Answer 2

Answer:

$a_{1}$ = 1/2

$a_{n}$ = $a_{n-1}$ * $\frac{4}{3}$

Step-by-step explanation:

plug 1 into $a_{n}$=1/2(4/3)^n−1  to find $a_{1}$

=1/2(4/3)^1−1

$a_{1}$ = 1/2 (4/3)^0

$a_{1}$ = 1/2 * 1

$a_{1}$ = 1/2

$a_{n}$ = $a_{n-1}$ * r where r is the ratio

since (4/3) is being taken to an exponent, (4/3) is r

$a_{n}$ = $a_{n-1}$ * $\frac{4}{3}$
