Calculate Question 4 Calculate n Question 5 Given the geometric series: a. Show that the series converges. b. Calculate the sum to infinity of the series. c. Calculate the sum of the first 8 terms of the series, correct to two decimal places. d. Use your answers to b and c to determine correct to two decimal places. Question 6
Geometric series are among the simplest examples of infinite series, and they played an important role in the early development of calculus. Geometric series are used throughout mathematics, and they have important applications in physics, engineering, biology, economics, computer science, queueing theory, and finance.
