Question

Find the mean term, if the other two term of a continued proportion are 15 and 60

Answer 1

Answer:

√[15×60)

=√900

=30.

Step-by-step explanation:

lets, a=15, b=? c=60.

a/b = b/c

b² = ac

b= √[15×60)

b=30

Answer 2

Answer:

Ans : Mean Term = 30

Step-by-step explanation:

Let The Mean Terms Be x

Proportion :

15 : x :: x : 60

Product Of Means = x × x = x²

Product Of Extremes = 15 × 60 = 900

Product Of Means = Product Of Extremes

x² = 900

x = √900

x = 300

∴ The Means Terms In The Continued Proportion Are 30.
