Note: To get [latex]50[/latex], find the midpoint between 42 and 58, which is just the average of the two endpoints = [latex]\frac{42+58}{2}=50[/latex].
Give an example of a number that is in this interval.
There are infinitely many numbers that can be within this interval. For example: [latex]43, 45.5, 50\frac{2}{3}, 57.99[/latex].
Give an example of a number that is not in this interval.
There are infinitely many numbers that are outside of this interval. In fact, any numbers below [latex]42[/latex] or above [latex]58[/latex] will be correct. For example: [latex]-15, 0, 40\frac{2}{3}, 58.01,12345.67[/latex].
