Question

The 1st , 3rd and 4th terms of a proportion are 12,8,14 respectively. find the second term

Answer 1

Answer:

second term = 21

Step-by-step explanation:

Given The 1st , 3rd and 4th terms of a proportion are 12,8,14 respectively.

Let the second term = x

$12:x::8:14$

$\implies product \:means =product \:of \:extremes$

$\implies x \times 8 = 12\times 14$

$\implies x =\frac{12\times 14}{8}$

$\implies x = 21$

Therefore,

second term (x)=21

Answer 2

Answer:

Answer:

second term = 21

Step-by-step explanation:

Given The 1st , 3rd and 4th terms of a proportion are 12,8,14 respectively.

Let the second term = x

12:x::8:1412:x::8:14

\implies product \:means =product \:of \:extremes⟹productmeans=productofextremes

\implies x \times 8 = 12\times 14⟹x×8=12×14

\implies x =\frac{12\times 14}{8}⟹x=

8

12×14

\implies x = 21⟹x=21

Therefore,

second term (x)=21
