The number of seats in row 20 is; 86 seats
<h3>What is the Arithmetic Sequence?</h3>
We are going to use the arithmetic sequence formula since we require the previous term in a sequence.
The arithmetic sequence formula is;
aₙ = a + (n − 1)d,
where;
a is the first term of the sequence
n is the position of the term in the sequence
d is the common difference
aₙ is the nth term of the sequence.
Our sequence is 10, 14, 18, 22 up to row 20.
Using the sequence formula;
a_20 = 10 + (20 − 1)4.
a_20 = 10 + (19* 4)
a_20 = 10 + 76
a_20 = 86.
Thus, the number of seats in row 20 was 86 seats.

Answer: 1%
Explanation:
"According to the Environmental Protection Agency, each additional 100 pounds on a vehicle can reduce its fuel efficiency by 1%. Carrying open cargo (i.e., on flatbeds) is also less fuel-efficient than carrying cargo inside a closed truck."

Graphs are used to represent functions and equations
<h3>How to determine the graph of the function</h3>
The equation of the function is given as:
f(x)=3sin(x/4+1)-1/2
The above function is a sine function.
So, we make use of the sine graph to represent the function f(x)
Set x = 0.
So, we have:
f(0) = 2.204
This means that, the graph of the function f(x) passes through (0,2.204)
See attachment for the graph of the function
