In a hockey arena the frist row has 276 seats the second row has 288 seats and the thrid row has 300 seats. each row after this continues to increase by the same number. if the arena has a total of 6?

To determine the number of seats in the first six rows of the arena, we first identify the pattern in the number of seats: the first row has 276, the second has 288, and the third has 300, indicating an increase of 12 seats per row. Continuing this pattern, the fourth row would have 312 seats, the fifth row 324 seats, and the sixth row 336 seats. Adding these together, the total number of seats in the first six rows is 276 + 288 + 300 + 312 + 324 + 336 = 1,836 seats.
