Answer:
4, 12, 36, 108 is set of geometric sequence.
Step-by-step explanation:
Given : geometric sequence.
To find : Which set of numbers is a geometric sequence.
Solution : We have given geometric sequence.
In a Geometric Sequence each term is found by multiplying the previous term by a constant.
Like : {a, ar, ar², ar³, ... }, where , a = first term , r = common ration .
We can see sequence 4, 12, 36, 108 in form of 4 , 4*3 , 4 (3)² , 4( 3)³.
Here, common ration is 3.
Therefore, 4, 12, 36, 108 is set of geometric sequence.
