Question

What is geometric mean between 3and243?​

Answer 1

Answer:

$\sqrt{3 \times 243 } \\ = \sqrt{3 \times 3 \times 3 \times 3 \times 3 \times 3} \\ = 3 \times 3 \times 3 \\ = 27$

Answer 2

Let the geometric mean be a1,a2,a3,a4,a5. Then

1/3, a1, a2,a3,a4,a5,243 from GP. Here 1/3 is the 1st term and 243 is the 7th term. Let r be the common Ratio.
