Solution

The median is the middle number in a set of odd numbers. As such, we do have from stem that \(b+2=5\) so \(b=3\)

It follows that the values of the five terms are \(\frac{0+2+5+6+7}{5}=\frac{20}{5}=4\)

The answer is \(B\)

Thank you. We had a mismatch when updated the questions with the new timer.
