A geometric series has constant ratio between consecutive terms. Hence when we take the ratio $r (n)=a_ {n+1}/a_n$ for an arbitrary series $\sum_k a_k,$ we are measuring how far it is …

Find the common ratio of the geometric series with the sum and the first term Ask Question Asked 12 years, 8 months ago Modified 3 years, 4 months ago

$\ {a_n\}$ is a geometric series with initial value $a_1$ and common ratio $r, \ {\log a_n\}$ is an arithmetic sequence with initial value $\log a_1$ and common difference $\log r$

The first term is $8$ and the common difference is $d\neq0$. The first, fifth, and eighth terms of the progression are the first, second, and third terms, respectively, of a geometric progression …

A geometric sequence $u_n$ is a sequence which is defined recursively by (given $u_1$) $$u_ {n+1}=ru_n,\quad r\in \Bbb R $$ where the ratio $r$ is a given number.

Apr 29, 2019 · A geometric sequence has its first term equal to $12$ and its fourth term equal to $-96$. How do I find the common ratio? And find the sum of the first $14$ terms

Consider two integers in a geometric progression separated by some powers of the ratio $a$. Then it should be possible to extend the series in one direction infinitely to yield an infinite …
