65

Step-by-step explanation:

You would first figure out how they're increasing. So if we look at this we see that per three rows there are 6 more seats which means per row there are 2 more seats. And then you would do 20 - 6 = 14 to find how many more rows there are. Since, there are 14 more rows you would do 14 * 2 = 28 because there are 2 more seats per row. After getting 28 you would add that to how many seats are in row 6 because we know how many seats there are in row 6 and you would get 65.

Step-by-step explanation:

Step 1: Find the difference in number of seats between row 6 and row 3, and then divide by the number of rows you have to go through to get from row 3 to 6 (3 rows).

37-31=6

6/3=2

2 seats added per row

Step 2: There is 14 rows between row 6 and row 20 so...

14*2=28

Step 3: Add the amount of seats in row 6 to 28

37+28=65

Seats in row 20=65
