Exploring Real-Life Applications of Geometric Sequences

This video tutorial covers the application of geometric sequences in solving real-life problems. It begins with an introduction to the concept and formula of geometric sequences. The tutorial then provides two example problems: one on the growth of COVID-19 cases and another on bacteria population growth. Each example demonstrates how to use the geometric sequence formula to calculate future values. The video concludes with exercises for viewers to practice and encourages engagement through comments and subscriptions.

What is the main focus of this lesson?

• Linear equations

• Geometric sequences

• Quadratic equations

• Arithmetic sequences

Which formula is used to find any term in a geometric sequence?

• a_n = a_1 * n

• a_n = a_1 + (n-1)d

• a_n = a_1 * r^(n-1)

• a_n = a_1 / r^(n-1)

What real-life problems can be solved using the geometric sequence formula?
