Lesson Goals

  • Identify if a sequence is arithmetic.
  • Determine a recursive formula for an arithmetic sequence.
  • Determine the general term of an arithmetic sequence.
  • Solve questions about arithmetic sequences using the general term.

Try This

The first term in a sequence of real numbers is \(a\). Each subsequent term is calculated by adding \(d\) to the previous term. Write the first \(4\) terms of this sequence and determine the general term.
