The inside diameter ranges from 200 millimeters to 250 millimeters in increments of how many millimeters?

1 millimeter

2 millimeters

5 millimeters

Think about the spacing between successive values. The inside diameter runs from 200 to 250 millimeters, a total spread of 50 mm. If you step by 5 mm, you get 200, 205, 210, 215, 220, 225, 230, 235, 240, 245, and 250—ten equal gaps, each 5 millimeters. So the increment is 5 millimeters. The other options would either produce too many steps or too few steps to neatly land on the endpoints in a consistent sequence.
