Mixed module checkpoint

Check your understanding of sequences, series and discrete change with a mixed precalculus assessment. The problems combine term and sum notation, arithmetic and geometric structure, recursion, payment timing, infinite totals and geometric applications.

These twelve fresh items require method selection without topic cues. Work independently before consulting the explanations, which include answer checks and common errors. Both single-select and multiselect formats are included. Use the results to identify specific topics for further practice; a single score is not a certification of mastery. Extension-only induction and summation proofs are excluded.
