Of three numbers, the first number is 25 and the third number is 100. If the second number is the mean proportional between the first and the third numbers, find the value of the second number.
50
Mean proportional between two numbers a and b is \(\sqrt{ab}\).
\(\sqrt{25\times100} = \sqrt{2500} = 50\).
Hence, the value of the second number is 50.
