mark me as brainlist and follow me

Step-by-step explanation:

The third proportion to a and b is defined as the number x such that a,b,x are in a geometric progression.”

Now, here a=12,b=18 and ‘c’ is to be found.

So,

[math]\frac{12}{18}=\frac{18}{c} [/math]

[math] c=\frac{18\times 18}{12} [/math]

So, c=27

Therefore option (c) is correct.
