a, b, c are in continued proportion i.e. a : b :: b : c. Here, b is called the mean proportional of a and c, as the square of the middle term is equal to the product of 1st term and 3rd term. Also, if a : b :: b : c, then c is called the third proportional of a, b. Hence, Options A and B are correct.
