Question

find value of x in proportion in 15,18,x,126​

Answer 1

Answer x × 12 = 15 × 8, [Since, the product of the extremes = the product of the means]

x × 12 = 15 × 8, [Since, the product of the extremes = the product of the means]⇒ x = (15 × 8)/12

x × 12 = 15 × 8, [Since, the product of the extremes = the product of the means]⇒ x = (15 × 8)/12⇒ x = 10
