Question

What is the 6th term in the geometric sequence described by this explicit formula?

Answer 1

Answer:

-5120 that is Option C is correct.

Step-by-step explanation:

We have been given the explicit formula we need to find the 6th term of the geometric sequence from the given formula.

The formula is:$a_n=-5\cdot (4)^{n-1}$

To find 6th term we will put n=6 in the formula given we will get:

$a_6=-5\cdot 4^{6-1}$

After simplification we get:

$a_6=-5\cdot 4^5$

After further simplification we will get:

$a_6=-5120$

Therefore, Option C is correct.
