Conclusions are tied to visible reasoning

Generated keys distinguish sequence limits, partial sums, infinite-series convergence, endpoint behavior, and approximation error instead of collapsing them into a single answer.

Learning objective

What this activity builds

Distinguish a sequence limit from a finite or infinite series conclusion.

Worked example

What belongs in a complete solution?

The governing limit or test, its hypotheses, the calculation, and a precise conclusion.

The worked key preserves the reasoning that distinguishes similar-looking sequence and series tasks.

Teaching notes

Make the practice count

  • Have students name the mathematical object before choosing a method.
  • Require separate endpoint checks for power series.
  • Keep exact values and labeled approximations side by side.
