An amphitheater has 22 seats in the first row, 26 in the second, 30 in the third, and so on, for 30 rows. How many seats are in the amphitheater?

198 if thirty rows after the first three, 186 if thirty includes original three

Step-by-step explanation:

Formula if including or not original three:

4(x)+78=total (78 from adding originals 30+26+22)

Formula if including originals:

4(27)+78           (x=number of rows, clearly)

108+78=

186

Formula if Not including originals :

4(30)+78

120+78=

198
