Which formula can be used to describe the sequence?


-3, 3/5, -3/25, 3/125, -3/625

Af(x) = -3(1/5)^x-1
Bf(x) = -3(1/5)^x-1
Cf(x) = -1/5(3)^x-1
Df(x) = -1/5(-3)^x-1

Verified Answer :

apologiabiology

each term is multiplied by -1/5
first term is -3

an=a1(r)^(n-1)
for a1=first term
r=common ratio
n=which term


in this case
first term=-3
common ratio is -1/5
so

\(f(x)=-3( \frac{-1}{5})^{x-1}\)

none of them
oh, A and B are the same
the one that has the -1/5 inside is the one

The one that has the -1/5 inside is the one.

each term is multiplied by -1/5.

The first term is -3

What is the formula for the sequence?

\(a_n=a_1(r)^{(n-1)}\)

for a_1=first term

r=common ratio

n=which term

In this case

The first term=-3

The common ratio is -1/5

so, \(f(x)=-3(\frac{-1}{5} )^{(x-1)}\)

None of them A and B are the same

The one that has the -1/5 inside is the one.
