Answer:
A. arithmetic
Step-by-step explanation:
We are given the sequence 3, 6, 9, 12 and are asked to determine whether it is arithmetic, geometric, or neither.
Let's define the two different terms :
Arithmetic - Sequence where a certain number gets added or subtracted
Geometric - Sequence where a certain number gets multiplied or divided.
3, 6, 9, 12
If we try geometric, which would be explained with 3 * 2 to get 6, but then multiplying 6 * 2 gets you 12. Not 9. Therefore it is not geometric.
Try arithmetic, 3 + what = 6. 3. 3 + 3 = 6. 6 + 3 = 9. 9 + 3 = 12.
Arithmetic works, therefore arithmetic is the sequence.
