Lesson Ch 5 L 4

• Sequences- A Sequence is a list of things
  (usually numbers) that are in order.
• Two types
• Arithmetic
• Geometric

22
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

23
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, 1/3 divide by 3

9. Inversely Proportional
This word actually means.. a nonlinear
