Since the figure is not attached, below you can see a general explanation of the procedure to solve the exercise: </h3>
For this exercise you can apply the following formula, which is used to calculate the area of a trapezoid:

Where "B" and "b" are the bases of the trapezoid and "h" is the height.
So, substituting values into the formula and evaluating, you can find the area of trapezoid-shaped region.
Since the population in the trapezoid-shaped region is about 3,000 people, you can find the number of people per square mile dividing the population by the area of the region.
Then, the following expression represents the number of people per square mile in that region:

Answer:
325
Step-by-step explanation:
Notice you are adding 7 everytime.
So the sequence would be:
a(n) = 10 + 7n
n=0 gives a(0)=10, which is the first term.
so the 46th term has n=45.
a(45)=10 + 7*45=325
