Question

The Palace Theater has 25 rows. There are 26 seats in the first row with 2

additional seats on each consecutive row. How many seats are in the
theater? *

Answer 1

The theater has 698 seats.

Explanation:

So, the first row has 26 seats, and that's one out of 25 rows.

Let's find the amount in the following rows.

The following rows have an additional 2 seats, so:

28 × 24 = 672

Now, we add the other 26 seats from the first row:

672 + 26 = 698

And there's your answer.
