A number lying in the middle between two numbers.

The video tutorial explains how to find a number that lies in the middle between two numbers. It introduces methods to calculate the midpoint by either adding half the distance to the smaller number or subtracting it from the larger number. An example is provided to find a rational number between 1/6 and 7/6, demonstrating the use of a number line and calculating the distance between the numbers. The tutorial concludes by showing how to find the midpoint using the calculated distance.
