Question

HURRY 20 POINTS!!!!! Given the geometric sequence an = 6(5)n − 1, which of the following values for n lies in the appropriate domain for n? (1 point)


n = −1

n = 1

n = 0

They all lie in the domain

Answer 1

Answer:

n = 1

Explanation:

Here we have the following Geometric Sequence:

$a_{n} = 6(5)^{n-1}$

Where:

$a=6 \ \text{First term} \\ \\ r=5 \ \text{Common ratio} \\ \\ n: \ \text{Number of terms}$

The first term occurs when $n=1$. Next the second term occurs when $n=2$, the third term when $n=3$ and so on. Therefore, the appropriate value of n that lies on the domain for n is $n=1$
