The given situation above is an example of a geometric sequence with first term equal to three and the common ratio equal to 3. For the second day, Raul used 9 bags of cement. He used 27 bags on the third and 81 on the fourth. To answer the question, add the number of bags from second to fourth day. The answer is equal to 117 bags of cement.
Answer is 10.0 and adding in . Are easy :D
Answer:

Step-by-step explanation:
The first term is 9.
Term 1 is 9.
Term 2 is 9 - 3.
Term 3 is 9 - 2(3).
Term 4 is 9 - 3(3).
Term 5 is 9 - 4(5)
Notice the pattern in terms 3 through 5. For each term, subtract 1 less than the term number multiplied by 3 from 9.
For term n, you subtract 1 less than n times 3 from 9.
The nth term is 9 - (n - 1) * 3

Now we simplify the expression on the right side.


The expression for the nth term is

Let's see if it works.
n = 1

n = 2

n = 3

n = 4

n = 5

n = 6

As you can see, following this rule fro the nth term, we got the same first siz terms you got above. Our answer is correct.

Answer:
$12,088.55
Step-by-step explanation:
The formula for compounded interest is A = P(1+r/n)^n(t)
A= final amount
P = initial amount
r = rate of interest
n = amount of times it is compounded
t = time or amount of years
In this case n=4 because you are compounding quarterly which is 4 times a year and t will be 3 because you are looking for the amount after 3 years. r is .14 because 14% is .14 in decimal form.
