Arithmetic, Geometric, or neither? How do you know? 2, 4, 8, 16, ...

• Arithmetic, because it adds a constant value.

• Geometric, because it multiplies by a constant value.

• Neither, because it does not follow a constant pattern.

Arithmetic, Geometric, or neither? How do you know? -74, -49, -24, 1

• Arithmetic, because the difference between the numbers is constant.

• Geometric, because the ratio between the numbers is constant.

• Neither, because there is no constant difference or ratio.
