Answer:
B. -3, 3, -3, 3...
Explanation:
There's two types of sequences, arithmetic and geometric.
Arithmetic equations are sequences that increase or decrease by adding or subtracting the previous number.
For example, take a look at the following sequence:
2, 4, 6, 8, 10, 12, 14, 16, 18, 20...
Here, the numbers are increasing by +2. [adding]
So, this the sequence is arithmetic, since its adding.
Geometric sequences are sequences that increase or decrease by multiplying or dividing the previous number.
For example, take a look at the following sequence:
2, 4, 16, 32, 64, 128, 256, 512...
Here, the numbers are icnreasing by x2. [multiplying]
So, the sequence is geometric since its multiplying.
Based on this information, the correct answer is "B. -3, 3, -3, 3..." since its being multiplyed by -1.
