Lesson 3

• What is a geometric series?

  It is the sum of all the terms of a geometric sequence.
• What is another name for a geometric sequence?

  Geometric Progression
• How is a geometric sequence defined?

  A geometric sequence is defined as a sequence where each term is a multiple of the previous term.
• What is the common ratio in a geometric sequence?

  The common ratio is a number \( r \) that can be determined by dividing any term by the previous term.
• How can the common ratio \( r \) be determined in a geometric sequence?

  The common ratio \( r \) can be determined by dividing any term by the previous term.
