The sequences are classified, respectively, as:
Geometric, Arithmetic, Neither.
<h3>What is a geometric sequence?</h3>A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
In the first sequence, we have that:
Hence it is a geometric sequence.
<h3>What is an arithmetic sequence?</h3>In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.
In the second sequence, we have that:
d = -4 - 1 = 1 - 6 = 6 - 11 = 11 - 16 = -5
Hence it is an arithmetic sequence.
<h3>What about the third sequence?</h3>Hence it is neither arithmetic nor geometric.
