Answer 2

Answer the given questions based on the information in the passage

Explanation:

• Let the number of rows be denoted by 'x' and the total number of seats in a row be denoted 'y'.
• Then the number of seats in xth row can be calculated using a simple function 'y' in variable 'x'.
• Here, the number of seats in the first row is two and it keeps increasing by three seats in the next rows.
• Hence, we get the function y for the total number seats in xth row as,     $y=3(x-1)+2\ \ \ \ \ \ \ \ \ ->y=3x-1$  
• Now for the number of seats in the tenth row we have, $x=10$         $->y=3(10)-1\\->y=29$   --->Answer(i)
• Now for the number of seats in sixth row we have, $x=6$                      $->y=3(6)-1\\->y=17$     --->Answer(ii)
