Answer:
True.
Step-by-step explanation:
The explicit form for an arithmetic sequence is:
where 
is the first term and 
is the common difference.
The common difference here is 2 because the y's are going up by 2 while the x's are going up by 1.
Yes, the common difference is the slope.
So we have d=2.
The first term is 9.5 because that is what happens when x=1.
x is n.
y is 
.
So the answer is true.

You can also verify by plugging in numbers for n and see if you get the outputs mentioned in the pairs given:
Let n=1:
Let n=2:
Let n=3:
Let n=4:
Let n=5:
Let n=6:
We have confirmed that we get all 6 of the mentioned points using the equation they gave.
Answer:
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 1 • -6 = -6
Step-2 : Find two factors of -6 whose sum equals the coefficient of the middle term, which is 2 .
Answer:
$1,175.34
Step-by-step explanation:
To solve for the total amount after 7 years. We need to use the formula:
Let's first break down all the variables that we have.
P = 480
r = 13% or 0.13
n = 4 (Quarterly)
t = 7 years
Now we simply substitute the values into the formula.
The account will have $1,175.34 after the 7 year period.
