Answer:
Option A is the answer.
Step-by-step explanation:
If a sequence is given in the form of

Then the given sequence will be an arithmetic sequence if

Here d represents common difference.
Now we will check each option given in the question.
Option A.
0, 3, 6, 9, 12.....
As per definition

Therefore this sequence is an arithmetic sequence.
Option B.
1, 4, 9, 16, 25.......

Since difference between the terms is not common so the sequence is not an arithmetic sequence.
Option C.
200, 100, 50, 25.......

Since difference is not common in each term so it's not an arithmetic sequence.
Option D.
4, 12, 36, 108..........
Now common difference

So this sequence is not an arithmetic sequence.
Answer is Option A.
