Which of the following sequences is arithmetic?0, 3, 6, 9, 12, ...1, 4, 9, 16, 25, ...200, 100, 50, 25, ...4, 12, 36, 108, ...

Answer:
0, 3, 6, 9, 12 .....

Explanation:
An arithmetic sequence is defined as a sequence of numbers that increases or decreases by a constant value.
The values are increasing when the same number is added or subtracted onto the number.
The rest of the choices do not have a constant number being added or subtracted they are either:
multiplied: option (D),
divided: option (C),
a list of perfect squares: option (B).

The answer (A) had the constant of 3 added to each term increasing forever.
