F(1) = 5 f(n) = 3 · f(n − 1), for n > 2
What is the 7th term in the sequence?
Please answer this

a(7)=3645

Step-by-step explanation:

you have :

f(1) =a= 5

and from recursive rule: f(n) = r · f(n − 1) and f(n) = 3 · f(n − 1)

So r=3

then

a(n)=a*r^(n-1)

a(7)=5*3^(7-1)

a(7)=5*3^6=3645

hope this helps

y=x+9
