Lessons that teach this standard

• Arithmetic and Geometric Sequences

  How to tell an arithmetic sequence from a geometric one, how to write each recursively and explicitly, and why the explicit rules are linear and exponential functions.

• Arithmetic Series and Sigma Notation

  Add the terms of an arithmetic sequence with Sₙ = n(a₁ + aₙ)/2, write sums compactly in sigma notation, and use the formula for counting and money problems.
