Step-by-step explanation:

Answer 2

The given in the problem above is an arithmetic sequence with the first term equal to 4 and the common difference is 5. To determine the number of seats on row 23, use the formula,
 
                                         an = a1 + (n - 1) d

Solving for the 23rd term, 
 
                                          an  = 4 + (22) 5 = 114 seats

Therefore, the answer is there are 114 seats on the 23rd row.
