A theater has 43 seats in the first row, 47 seats in the second, and 51 seats in the third row. How many seats are there in row 17
To find the number of seats in row 17, we need to identify the pattern or rule that governs the seating arrangement in the theater.
Looking at the given information, we can see that the number of seats in each row increases by 4 as we move from one row to the next. Specifically, the first row has 43 seats, the second row has 47 seats (43 + 4), and the third row has 51 seats (47 + 4).
Based on this pattern, we can conclude that each subsequent row will have 4 more seats than the previous row.
To find the number of seats in row 17, we can use the formula:
Seats in nth row = Seats in first row + (n - 1) * 4
Plugging in the values:
Seats in 17th row = 43 + (17 - 1) * 4
Seats in 17th row = 43 + 16 * 4
Seats in 17th row = 43 + 64
Seats in 17th row = 107
Therefore, there are 107 seats in row 17.
To find the number of seats in row 17, we need to determine the pattern of the seat count.
In this case, we have a difference of 4 seats between each row.
The first row has 43 seats, with each subsequent row having 4 more seats than the previous row.
To find the number of seats in row 17, we can use the formula:
Number of seats in row 17 = Number of seats in the first row + (Difference in seats * (Row number - 1))
Number of seats in row 17 = 43 + (4 * (17 - 1))
Number of seats in row 17 = 43 + (4 * 16)
Number of seats in row 17 = 43 + 64
Number of seats in row 17 = 107
Therefore, there are 107 seats in row 17.
term(1) = 43
term(2) = 47
a = 43 , d = 4
term(17) = a + 16d
= 43 + 16(4) = 107
