3.11 Geometric Sequences — The Math That Makes Wealth Explode | Contemporary Mathematics
After this lesson you will be able to…
- Understand what geometric sequences are and their prevalence in the real world.
- Differentiate between arithmetic and geometric sequences based on their progression.
- Learn how the common ratio dictates the growth, decay, or oscillation of a sequence.
- Use the nth term formula to calculate any specific term in a geometric sequence.
- Calculate the number of ancestors in a specific generation using the nth term formula.
- Calculate the cumulative total of a geometric sequence using the sum formula.
- Understand the immense cumulative power of geometric growth with the chessboard rice problem.
- Explore how the sum of a shrinking geometric sequence approaches a specific limit.
- Understand how compound interest and investment doubling times are geometric sequences.
- Explain why more frequent compounding (e.g., monthly) leads to greater returns.
- See how geometric sequences explain rapid population growth in biology.
- Ponder whether real-world exponential growth always encounters physical limits.
