Answer:
Geometric sequence
Step-by-step explanation:
There are two types of number sequences: arithmetic sequence and geometric sequence.
An arithmetic sequence is where you need to add a certain common difference to the terms as the sequence progress.
A geometric sequence is where you need to multiply a certain common ratio to the terms as the sequence progress.
As you can observe from the sequence "2, -6, 18, ...", we need to multiply by -3 to get to the next number. Since we are multiplying, the sequence is a geometric one.
Hope this helps!
