Geometric Sequences Course
This course equips you with a strong grasp of geometric sequences through clear formulas, step-by-step derivations from first principles, and practical models for growth and decay like interest rates, population shifts, and discounts. Gain intuition to sidestep common exam mistakes, confidently handle geometric sums and infinite series limits, and apply these skills in advanced maths and real-world problem-solving scenarios.
