the first row of a movie theater has 15 seats and 3 additional seats in each subsequent row. how many seats are in the 14th row? how many seats in total are in the first 14 rows?

There are 54 seats in 14th row,

In the first 14th row the total seats are 483.

Step-by-step explanation:

Given,

The number of seats in first row = 15,

Also,  3 additional seats in each subsequent row,

⇒ The seats in second row = 15 + 3 = 18,

⇒ The seats in third row = 18 + 3 = 21,

⇒ The seats in fourth row = 21 + 3 = 24,

................................................, so on,........

Thus, the given situation can be written as an AP,

15, 18, 21, 24,...........

Having first term, a = 15,

Common difference, d = 3,

Thus, the number of seats in 14th row,

Also, the total number of seats in total in the first 14th seats,
