Step-by-step explanation:

Let the second term be x

Proportion = 6:x::12:36

= 12x= 216

= x= 216/12

x= 18

therefore the second term is 18.

Proof:

of 18 that is correct answer:

(put the value of X in proportion)

therefore = 6:18::12:36

= 6*36=18*12

= 216=216

therefore 18 is correct answer.
