Question 1: Find the sum of geometric series if a = 3, r = 0.5 and n = 5. Solution: Given: a = 3 r = 0.5 n = 5 s n = a ( 1 − r n) 1 − r The sum of five terms is given by S 5 = 3 ( 1 − ( 0.5) 5) 1 − 0.5 = 5.8125 Question 2: Find S 10 if the series is 2, 40, 800,….. Solution: From the given, a = 2 r = 20
WebA geometric sequence is a sequence of numbers in which each term is obtained by multiplying the previous term by a fixed number. It is represented by the formula a_n = a_1 … WebAn infinite geometric series is the sum of an infinite geometric sequence. When − 1 < r < 1 you can use the formula S = a 1 1 − r to find the sum of the infinite geometric series. An infinite geometric series converges (has a sum) when − 1 < r < 1, and diverges (doesn't have a sum) when r < − 1 or r > 1. In summation notation, an ...
