Answer:
1
Step-by-step explanation:
Here, we may use Geometric Progression
The sequence follows as:
27, 18,12,...
The first term (a)= 27
27/18 = 18/12
common ratio = 1.5
Let fourth term be x
Therefore , 12/x = 1.5
=> x= 12/1.5 = 8
Note that both sides were multiplied by 5.
So that would be "Multiplication Property of Equality."
Basically, this property states that if a=b, then ac = bc.
