The video tutorial explains how to calculate the seating capacity of an auditorium with 52 rows, where the number of seats in each row forms an arithmetic series. Starting with 24 seats in the first row and increasing by 4 seats per row, the tutorial demonstrates how to find the common difference, calculate the 52nd term, and use the arithmetic series formula to find the total number of seats. The final result is a total of 6,552 seats.
