Answer: -9n+20
This is the same as 20-9n
================================================
Explanation:
The jump from 11 to 2 is "minus 9"
The jump from 2 to -7 is also "minus 9".
Assuming this pattern continues on, we have an arithmetic sequence with
- a = 11 = first term
- d = -9 = common difference
The nth term can be found like so
Let's check the answer by trying n = 3
This shows the third term is -7, which matches what the original sequence shows. The answer is partially confirmed. I'll let you check the other values of n. You should get 11 when trying n = 1, and you should get 2 when trying n = 2.
<h2>Answer</h2>
f(x) = 190(1.15)x
<h2>Explanation</h2>To solve this, we are going to use the standard exponential function:
Where
is the final price after
years
is the initial price
is the rate in decimal form
is the time in years
We know from our problem that the initial price is $190, so . Now to convert the rate, 15%, to decimal form, we are going to divide it by 100%, so
. Let's replace the values:
