Let

be the n'the term of the sequence.
The first term of the sequence is

the second

is 8
the third term

is 4
the fourth term

is 2
the fifth term

is 1
We notice that:
i) the values of the terms are powers of 2, and decreasing:

ii) we also notice that the subscript integer of a, and the power of 2 at that term, add to 5.
thus the general term of the sequence is given by:

.
to fit the choices of the question, we can modify this formula as follows:

The average rate of change from n=1 to n=3 is defined as:


can be found using the general formula,

,
thus the average rate of change is (4-16)/2=-12/2=-6
Answer:

,
average rate of change=-6
Answer:
The will be answer is 7216
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Because Bacon is good
75
Reduction of 12
3 x 4 = 12
Increase of 10
5 x 2 = 10
75 - 12 = 63
63 + 10 = 73
Change = 2 inches (75 - 73)
So basically, we are looking for the amount of tip that the rider gave the driver if the driver paid a total of 23.25 dollars. So in order to get the tip, we just have to multiply the total cost of the taxi, which is 23.25, to the percentage of the tip which is 15%. So in order to get the final answer, we have to express the formula as this. 23.25 x 0.15. So if we would solve this equation, we will get an answer of 3.4875. So the tip that was given was 3.4875
