The mayor wants the number of seats in the arena to be between 3 000 and
4 000. One ring of seats all the way around the event space is considered a
row, and row 1 is considered to be the row closest to the space event. He
wants the number of seats in each row to form an arithmetic sequence, increasing by the same number in each subsequent row. Your task is to
decide on the total number of seats in the arena by designing a seating
arrangement that has a reasonable number of rows by determining:
a. The number of seats in the first row.
b. The number of rows required.
c. The number of seats by which each row increases.
d. The number of seats in the last row.
e. The total number of seats in the arena.
