Lesson Ch 5 L 4 Sequences- A Sequence is a list of things (usually numbers) that are in order. Two types Arithmetic Geometric

Arithmetic An arithmetic sequence goes from one term to the next by always adding (or subtracting) the same value. For instance 2, 5, 8, 11, 14, adds 3 7, 3, –1, –5,. Subtracts 4

Geometric A geometric sequence goes from one term to the next by always multiplying (or dividing) by the same value. So 1, 2, 4, 8, 16, multiply by 2 and 81, 27, 9, 3, 1, 1/3divide by 3
