Partial sums of geometric series
Partial sums of geometric series
What you'll learn
- Identify the first term, common ratio, and number of terms in a given geometric series and express them in a mathematical formula with 100% accuracy.
- Solve for the partial sum (Sn) of a finite geometric series, given the first term (a), common ratio (r), and number of terms (n), with at least 80% accuracy on a summative assessment.
- Apply the formula for the sum of an infinite geometric series to determine convergence or divergence, and calculate the sum if convergent, justifying the answer with clear mathematical reasoning in at least 3 out of 4 opportunities.
- Explain the derivation of the formula for the partial sum of a geometric series using algebraic manipulation and mathematical induction in a written explanation that demonstrates comprehensive understanding.
