Answer:
, all integers where n≥1
Step-by-step explanation:
we know that
The explicit equation for an arithmetic sequence is equal to
a_n is the th term
a_1 is the first term
d is the common difference
n is the number of terms
we have

Remember that
In an Arithmetic Sequence the difference between one term and the next is a constant, and this constant is called the common difference.
To find out the common difference subtract the first term from the second term

substitute the given values in the formula

The domain is all integers for 
Answer:
y = |x|
Step-by-step explanation:
Since it's absolute value, number will turn out positive
Answer:
Alan received 350 votes
Step-by-step explanation:
David received 250 votes
Shari received 400 votes
1,000 - 250=750
750 - 400 = 350
Answer:
The limit of the function as x approaches 1 is ∞
Vertical asymptote; x = 1
Step-by-step explanation:
The graphical approach to evaluating limits involves graphing the function, the graph of the function
is contained in the attachment below.
The red vertical line is the graph of x = 1. As we approach the line x = 1 from the left, the value of the function, that is y becomes large and large indefinitely. That is the value of the function approaches infinity. The same case applies when we approach the vertical line x = 1 from the right.
Also noticeable is the fact that the function approaches the line x = 1 asymptotically. The function gets closer and closer to this line but actually never touches it. Therefore, the line x = 1 is our vertical asymptote of the function given
