Question

a,b,c are in continued proportion. What is mean proportional? Write formula for mean proportional​

Answer 1

Step-by-step explanation:

If a , b and c are in continued proportion then the ratio between a and b is the

same as the ratio between b and c.

or , a : b : : b : c.

or , b×b = a×c.

or , b^2 = a.c.

or , b =√(a.c), thus b is mean proportional of a and c.
