In a theater there are 12 seats on the first row and 16 on the second row. The number of seats in a row continues to increase by 4 each additional row. Write an explicit rule to model the sequence formed by the number of seats in each row.

 

 

equation:Nseats(row)=12+4(row-1)

 

question: would i replace row with n?

Seats  in row  N  =

 

12  + 4 ( N - 1)

 

Note ...for example.... that on  row 2  we have 

 

 12 + 4 (2 - 1)  = 

 

12 + 4(2 - 1)  = 

 

12 + 4(1)  =

 

16 seats
