Answer:

Neither.

Step-by-step explanation:

you are correct about the pattern, so it's not adding the same number and not multiplying by the same number. So it's neither.

It can't be A because both are false.

It can't be B because there is no common ratio.  

It can't be C because the sequence has no common difference.

Thus, you can this sequence a related to Fibonacci sequence (only you subtract, not add):  

ex. 3331282419  

\/ \/ \/ \/  

2 3 4 5  

meaning 33-2=31  

31-3=28  

28-4=24

So, the answer is D.
