Question

Find the third term of a proportional if the first, second and fourth terms are 24, 36, 126

Answer 1

Answer:

The third term of a proportional will be: 84

Step-by-step explanation:

We know that if a, b, c and d are in proportion, then:

$\:\:a\:\times \:d\:=\:b\:\times \:c$

In our case, we are given the first, second, and fourth terms are $24, 36, 126$

$a = 24$

$b = 36$

$d = 126$

and we have to determine the third term 'c'.

as we know that  if a, b, c, and d are in proportion, then:

$\:\:a\:\times \:d\:=\:b\:\times \:c$

Thus,

substituting a = 24, b = 36, d = 126 to determine

$24\:\times \:126\:=\:36\:\times \:c$

$c=\frac{24\:\times \:\:126}{36}$

$c=\frac{3024}{36}$

$c = 84$

Thus, the third term of a proportional will be: 84
