Answer:

<em><u>A theater has </u></em><em><u>60 seats</u></em><em><u> in the first row, 68 seats in the second row, 76 seats in the third row,</u></em>

<em><u>and so on in the same i</u></em><em><u>ncreasing pattern</u></em><em><u>. If the theater has</u></em><em><u> 20 rows of seats, how many seats are in the theater?</u></em>

220 seats in the theater.

So if the increasing pattern is +8, and we need to determined how many seats there will be if there where 20 rows, then you would need to multiply.

1. 8 x 20 = 160

2. 160 + 60 = 220
