ANSWER
EXPLANATION
An arithmetic has a constant difference .
We check to see which of the given sequences has a constant difference.
0,2,4,6,8,... has a constant difference of
hence it is an arithmetic sequence.
1,2,4,8,... is not an arithmetic sequence because there is no constant difference.
1,4,8,13,... is also not an arithmetic sequence because there no constant difference.
The first option is correct.
