Explanation:
Here, we want to get the sequence type
In an arithmetic sequence, the difference between terms is the same
For a geometric sequence, the division of a succeeding term by a preceding term would yield the term called the common ratio
Now, let us consider the differences:
This means that the sequence is not arithmetic
Now, let us test if geometric
Mathematically, we have that as:
This means that the given sequence is geometric
