110
114
115
119
Score: 2 of 2

Answer 1

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. 

Answer 2

There are 114 seats in the 23rd row

How to determine the number of seats?

The given parameters are:

Initial, a = 4

Common difference, d = 5

The nth term of an arithmetic sequence is:

Tn = a + (n - 1) * d

When n = 23, we have:

T23 = 4 + (23 - 1) * 5

Evaluate

T23 = 114

Hence, there are 114 seats in the 23rd row
