Instructional Ideas
- Have the class create a graphic organizer summarizing how to find recursive and explicit formulas for sequences
Classroom Considerations
- Learners should have prior experience with both arithmetic and geometric sequences
- Note that a major difference in the treatment of geometric sequences in Algebra II (compared to Algebra I) is that the indices start at zero
Pros
- Lesson reviews concepts before diving into more complex problems
- Teacher guide contains a comprehensive answer key for all problems
Cons
- None
