We say that the sum to infinity is 8, or The sum to infinity of the series is calculated by , where is the first term and r is the ratio between each term. For this series, where and , which becomes . The sum of an infinite number of terms of this series is 8. This means...
简单英文数学问题(geometric sequence)find the sum to infinity of a geometric sequence whose sum to three terms is 3968 with a second term of 640please process,thanks 答案 geometric sequence是等比数列呀那么设公比是q就有 640/q+640+640q=3968所以640q^2-3328q+640=0q=1/5 or q=5q=5数列极限...
What is sum to infinity of a geometric sequence? 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...
