How to Find the Sum to Infinity of a Geometric Series The sum to infinity of a geometric series is given by the formula S∞=a1/(1-r), where a1 is the first term in the series and r is found by dividing any term by the term immediately before it. a1 is the first term in the ...
Infinite Geometric Series Solved Examples Lesson Summary FAQs Activities 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...
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...
