Instructional Ideas
- Use the video to introduce arithmetic and geometric sequences
- Pause video to allow learners to answer posited questions before viewing answers
Classroom Considerations
- Video refers to the general term of a sequence; be sure learners know that this terminology is used to indicate what is also known as the explicit formula of a sequence
Pros
- Concept video touches upon the fact that there is an explicit and recursive formula for each sequence
Cons
- Concept video only uses examples of increasing sequences, though it does mention that sequences can be decreasing
