Classify the sequence (an)=(-9,-3,0,6…)as arithmetic, geometric, or neither. If there is not enough information to classify the sequence, choose not enoughinformation

an = (-9,-3,0,6 )
The sequence has not a common difference ( it's not an arithmetic sequence )
6/0 = no
0/3 = 0
-3/-9= 0.33
It has no common ratio ( it is not a geometric sequence )
Answer: C. neither
