Two sequences are shown on the graph below.  Sequence A is modeled by the black points, and sequence B is modeled by the gray points.

Which sequence is arithmetic?  Explain your reasoning.

• Sequence A, because it follows a linear pattern

• Sequence A, because it DOES NOT follow a linear pattern

• Sequence B, because it follows a linear pattern

• Sequence B, because it DOES NOT follow a linear pattern
