in a auditorium the first row has 30 seats and every row after that as 4 more than the row in front of it how many seats are in the 25 row

30 + 4(25 - 1) = ?

126 To determine the number of seats in the 25th row of an auditorium, we need to find the pattern in the increase of seats from one row to the next.

Given that the first row has 30 seats, we can establish that the second row will have 30 seats + 4 seats = 34 seats.

For the third row, we add 4 seats to the previous row: 34 seats + 4 seats = 38 seats.

We can observe that for each subsequent row, we add 4 seats.

To find the number of seats in the 25th row, we can use the formula:

Number of seats in the nth row = Number of seats in the first row + (n-1) * 4

Plugging in the values:

Number of seats in the 25th row = 30 + (25-1) * 4 = 30 + 24 * 4 = 30 + 96 = 126

Therefore, there are 126 seats in the 25th row of the auditorium.
