Answer 1

The total number of seats in the first seven rows of a theater, based on the given pattern, is 56 seats.

Step-by-step explanation:

The question asks us to determine the number of seats in the first seven rows of a theater, given a pattern in a chart. Each row has two more seats than the previous row, starting with 2 seats in the first row.

To find the total number of seats in the first seven rows, we can calculate the number of seats row by row:

1. Row 1: 2 seats
2. Row 2: 4 seats
3. Row 3: 6 seats
4. Row 4: 8 seats
5. Row 5: 10 seats
6. Row 6: 12 seats (since each following row adds 2 more seats)
7. Row 7: 14 seats

Add the number of seats in each row to find the total:

2 + 4 + 6 + 8 + 10 + 12 + 14 = 56 seats

Therefore, the correct answer is 56 seats in the first seven rows of the theater, which corresponds to option d.
