Answer:
The third term of a proportional will be: 84
Explanation:
We know that if a, b, c and d are in proportion, then:

In our case, we are given the first, second, and fourth terms are




and we have to determine the third term 'c'.
as we know that if a, b, c, and d are in proportion, then:

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




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