Question

The seats at a local baseball stadium are arranged so that each row has five more seats than the row below it. If there are 4 seats in the 1st row, how many seats are in row 23?

Answer 1

Givens:

a = 4; n = 23; d = 5

Formula

L = a + (n - 1)*d

Substitute and solve

L = 4 + (23 - 1)*5

L = 4 + 22*5

L = 4 + 110

L = 114 Answer
