Question

I need help with this question?

Answer 1

One seat is increased in each row as it goes higher....

Answer 2

It looks like the rows are increasing by 1 seat in each row:

4th row would have 23 seats

5th would have 24 seats

6th would have 25 and so on...

The last row of this section, since there are 12 rows, has 31 seats in it.
