Answer:
Option 1 the given sequence is a geometric.
Step-by-step explanation:
We have been given with the series
Arithmetic sequence is the sequence in which difference between consecutive terms is same that is common difference d
here
here
We can see the difference is not same
Hence, the given sequence is not arithmetic sequence.
Geometric sequence is the sequence in which ratio of consecutive terms is same that is common ratio r
here
here
here
We can see the ratio is same.
Hence, given sequence is geometric
Therefore, Option 1 is correct given sequence is geometric.
