Answer:
[tex]Geometric[/tex]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:
[tex]2-1\text{ is not the same as 4-2 }[/tex]This means that the sequence is not arithmetic
Now, let us test if geometric
Mathematically, we have that as:
[tex]\frac{4}{2}=\frac{2}{1}=\frac{8}{4}=\frac{16}{8}\text{ = 2}[/tex]This means that the given sequence is geometric
