   We will learn how to find the mean and third proportional of the set of three numbers. If x, y and z are in continued proportion then y is called the mean proportional (or geometric mean) of x and z. If y is the mean proportional of x and z, y^2 = xz, i.e., y = +\(\sqrt{xz}\).

   Third Proportional. Similar to the f=definition of the fourth proportional, we define the term known as the third proportional. The third proportional of a proportion is the second term of the mean terms. For example, if we have a:b = c:d, then the term ‘c’ is the third proportional to ‘a’ and ‘b’. Mean Proportional

   (1) Find the mean proportion between 4 and 9. (2) Find the third proportional to 12 and 30. Solution: (1) Let the mean proportion be X => 4, X and 9 are in continued proportion. 4: X = X: 9 X × X = 4 x 9 X2 = 36 X = 6 Ans. (2) Let X be the third proportional => 12, 30 and X are in continued proportion
