Search for key terms or text.

In this lesson, you learned how to:

  • Explain why different equations can represent the same sequence.

Here are the activities that helped you reach those goals:

  • 4.18.1 Repeated Operations
    • In this activity, you looked at different ways to represent repeated addition with multiplication and exponents.
  • 4.18.2 Identifying Domain for a Function
  • 4.18.3 Define an Arithmetic Sequence by the nth Term
    • In this activity, you learned how to represent arithmetic sequences using an explicit general rule.
    • 4.18.3: Self Check
    • 4.18.3: Additional Resources
  • 4.18.4 Define a Geometric Sequence by the nth Term
    • In this activity, you learned how to represent geometric sequences using an explicit general rule.
    • 4.18.4: Self Check
    • 4.18.4: Additional Resources
  • 4.18.5 Interchanging between Formulas
    • In this activity, you learned that arithmetic and geometric sequences can be written using the recursive definition and the nth term. It is possible to use them interchangeably.
    • 4.18.5: Self Check
    • 4.18.5: Additional Resources
  • 4.18.6 Different Types of Equations
    • In this activity, you looked at how the same arithmetic sequence was represented recursively and with the nth term.

After these activities, you completed the following practice:
