Calculating the Number of Seats in the Second Row of the Cinema Hall

To calculate the number of seats in the second row of the cinema hall, we can use the given information that in each subsequent row, there are 4 seats less than in the previous row. We are also given that there are 64 seats in the eleventh row of the cinema hall.

Let's denote the number of seats in the second row as x.

We can use the given information to form an equation to solve for x:

11th row: 64 seats 10th row: 64 + 4 seats 9th row: (64 + 4) + 4 seats ... 2nd row: (64 + 4*9) seats

Calculating the Number of Seats in the Second Row

Using the given information, we can calculate the number of seats in the second row as follows:

64 + 4*9 = 64 + 36 = 100

Therefore, there are 100 seats in the second row of the cinema hall.

This calculation is based on the given information and the pattern of decreasing seats in each subsequent row
