Question

a,b,c are in continued proportion if a=3 and c=27 ,then find b​

Answer 1

Answer:

b = 9

Step-by-step explanation:

If the terms are in proportion, it means

$\frac{a}{b} = \frac{b}{c} \\ \frac{3}{b} = \frac{b}{27} \\ {b}^{2} = 27 \times 3 = 81 \\ b = \sqrt{81} = 9$

Answer 2

Solution:

It is given that 3, b, 27 are in continued proportion. Thus, the value of b is 9.
