Question

A theater has 43 seats in the first row. There are 49 seats in the second row, 61 seats in the third row, and 79 seats in the fourth row. If this pattern continues, how many seats are in the seventh row?

Answer 1

43 to 49 is 6
49 to 61 is 12
61 to 79 is 18
add 6 to each
79=4th row
79+18+6=79+24=103
103+24+6=103+30=133
133+30+6=133+36=169

7th row=169 seats
