Given the geometric sequence an = 3(−4)^(n − 1), which of the following values for n lies in the appropriate domain for n?

n = 0
n = −1
n = 1
They all lie in the domain

Answer 1

The answer to your question is C. n=1

Answer 2

values of n all lies in the domain .

Explanation:

Given : Given the geometric sequence
`a_(n)`=
`3(-4)^(n-1)`.

To find : which of the following values for n lies in the appropriate domain for n.

Solution : We have given that
`a_(n)`=
`3(-4)^(n-1)`.

Domain : the set of input values for which function is defined or real.

Domain of
`3(-4)^(n-1)` are all real numbers (-∞ , ∞).

Therefore, values of n all lies in the domain .
