110
114
115
119
Score: 2 of 2

Respuesta :

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.

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
