Determine which sampling method is being described in the following scenario?

"A math teacher wanted to select a sample of students based upon two periods of Math 3 classes. The instructor numbered each student starting with 1 and ending with 70. The teacher then decided to take every 10th person wherever he/she started. The teacher used a calculator to randomly select the value 45. At that point the teacher counted down the list of students to the 10th person. That 10th person is added to the sample."
