Old mathematicians never die; they just lose some of their functions. Studying sequences gives scholars an opportunity to use a new notation. Learners write functions to model arithmetic and geometric sequences and use them to find new terms.

Instructional Ideas
- Use the practice problems as board work to find misconceptions
- Have pairs of pupils write sequences for each other, and tell each individual to identify the type of sequence and write an equation to model it
Classroom Considerations
- Learners may find sequence notation confusing, so spend time developing the notation with several examples
- Lesson begins a series of 20 algebra lessons
Pros
- Thoroughly explains the notation related to sequences
- Pays attention to the new vocabulary pupils will need to understand the concept of sequences
Cons
- Introduces a formula early in the process, which doesn't give pupils time to develop a thorough understanding of the sequence patterns
- Refers to the explicit formulas as recursion formulas; learners may confuse this with the recursive formulas which are different
