Question

If three numbers are in G.P whose sum is 21 and their product is 216, then find them.
give the correct answer​

Answer 1

The three nos are are 12, 6 and 3

If we add then it becomes 21 and multiply then It becomes 216. Then, 216÷3=72. now, 12 + 6 + 3 = 21. and 12 × 6 × 3 = 216.

Answer 2

Answer:

hope it helps you

Step-by-step explanation:

given that the continued product of three numbers in G.P is 216 and the sum of the product of that in pairs is 156. We have to find the numbers. Therefore, we get r = 3 and \[r=\dfrac{1}{3}\]. Hence, we get three numbers in G.P as 2, 6, 18, or 18, 6, 2.
