☘️ Question :

If the numbers x, 6 and 9 are in continued proportion, find the value of x.

☘️ Answer :

x = 49.

☘️ Solution :

As we know :

• Product of extremes = Product of means

Since x, 6 and 9 are in continued proportion, we have :

ㅤ x : 6 : : 6 : 9

⟹ x × 9 = 6 × 6

⟹ x = 6 × 6/9

⟹ x = 4

Hence, x = 49.
