The given sequence is 4,12,36,108....
Here we can observe the first term = 4 , and so on.
The common ratio (r)=
Since the common ratio is greater than 1,
Therefore the sum of the geometric series =
Since we have to find the sum of first seven terms, so n=7
=
=4372.
Therefore, option C is the correct answer.
D or c I think I’m not 100% positive but I would lean more to answer d
