The number of seats in the theater's rows represent an ARITHMETIC SEQUENCE. In an arithmetic sequence, the next term in the sequence is found by adding a constant (a set amount), called the common difference.

For the theater, there are...
17 seats in row 1
20 seats in row 2
23 seats in row 3
26 seats in row 4

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
