What is the recursive rule for this given sequence? 2, 6, 18, 54, 162
A) f(n)= f(n-1). 2
B) f(n)= (3). 27-1
C) f(n)= f(n-1). 3
f(n)=(2). 39-1

C

Step-by-step explanation:

I'm going to assume that when you write a period you mean *

A recursive rule is pretty much asking "how do i get a specific number in the sequence"

we can see that each time we mulitply by 3 which means that to get say the 3rd number we would take the 2nd and mulitply it by 3

which means we can write

f(n-1)*3

which is C

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

it is not that hard all u have to do is plot the graph
