Answer:
A
Step-by-step explanation:
Geometric sequences are ones that have a common ratio (ie. the common ratio is multiplied by the previous term to get the next term).
In A, the common ratio is 3. 2 * 3 = 6. 6 * 3 = 18, etc.
In B, C, and D, they are arithmetic sequences.
That means that a number is added, not multiplied, by the previous term to get the next term.
B: 1 + 4 = 5, 5 + 4 = 9, etc.
C: 0 + 5 = 5, 5 + 5 = 10, etc.
D: 5 - 4 = 1, 1 - 4 = -3, etc.
