Question

for the following geometric sequence find the recursive formula. {1, -3, 9, ...}

Answer 1

Answer:

$g_{n}=g_{n-1} *-3$

Step-by-step explanation:

A recursive formula is $g_{n}=g_{n-1} *r$.  N is the number of terms and r is the rate of change.  R here equals -3 because you are multiplying by -3 eachtime.  Therefore, the recursive formula is $g_{n}=g_{n-1} *-3$

Answer 2

The answer is : Gn= Gn- 1* -3
