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

Sphinxa [80]

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.

Please help.. will mark Brainliest!

PolarNik [594]

Answer:

128 degrees, so C is again the answer.

Step-by-step explanation:

Since angles 3 and 11 are corresponding(from your previous question), angles 1 and 11 will add up to 180 degrees, since a line is that long. Therefore your answer is 180-(degrees of angle 1)= 180-52= 128
