A theater has 32 rows of seats. If there are 26 seats in the 1st row, 30 in the 2nd, 34 in the 3rd, and so on, how many seats are there in all? Assume the pattern continues.

• 2,791 seats

• 2,803 seats

• 2,816 seats

• 2.829 seats

These are terms between any two non-consecutive terms of an arithmetic sequence.
