The sum of an infinite geometric sequence is 12 and the first term is 3. What is the
The sum of an infinite geometric series is of the form: S=a11−r where a1 is the first term and r is the ratio whose absolute value is less than 1. We know that the second term is the first term multiplied by the ratio. In other words: a1⋅r=1a1=1r Thus, the sum is the...
The infinite sum of a geometric sequence can be found via the formula if the common ratio is between -1 and 1. If it is, then take the first term and divide it by 1 minus the common ratio. How do you find the sum of an infinite geometric series? To find the sum of an infinite...
The sum of an infinite geometric series is 162 and the sum of its first n terms is 160. If the inverse of its common ratio is an integer, then which of
Infinite Geometric Series Sum: Sum of an infinite geometric series with a as initial term and r as common ratio is given by, ∑n=0∞arn=a1−r where |r|<1 We can write the given expression in this geometric series form and apply the formula above. Answer and Expl...
then we have an infinite geometric series. When {eq}|t| < 1 {/eq}, the sum of such a series is given by {eq}\displaystyle \frac{h}{1-t} {/eq}. Answer and Explanation: Given that: {eq}\displaystyle \sum\limits_{n = 3}^\infty {\frac{{{2.3}^{n...
解析 The sequence is not geometric or arithmetic because there is no common difference or common ratio between each term. Not a Geometric or Arithmetic Sequence The series given is not geometric. Therefore, the infinite sum cannot be calculated. No solution...

Re: How to find the limit of a sum of a series? I only know how to do this in the case of a geometric series. The sum of a geometric series is given by: If , then as n goes to infinity, becomes negligible. Therefore, the limit of the sum of an infinite geometric series ...
