Answer 2

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.
