What is the closed-form expression for the below sum of Geometric Progression (GP) sequence‚ S n ? S n a aR aR 2 ... aR n (1) where R is called the common ratio (between consecutive terms) of the GP sequence. The reason why we want to derive a clo...
一个英文数学题The first term of a geometric progression is 3 and the last term is 48.If each term is twice the orevious term,find the sum of the geometric progression.
A series is the sum of the terms of a well defined sequence. A geometric sequence is one in which each term is the product of the previous term and a given constant, and a geometric series is a series based on a geometric sequence. What is the sum of geometric progression? A geometric...

How do I calculate the sum of a geometric series? To know how to find the sum of a series in geometric progression, we can use either the finite sum formula or the infinite sum calculation. A geometric series can converge or diverge depending on the value of the common ratio rr. To de...
Sum of Geometric Sequence: In a geometric progression, if a is the first term and r is the common ratio then sum of its first n terms is defined as follows: {eq}S_n= \frac{a(1-r^n)}{1-r} {/eq} Answer and Explanation: Become a Study.com membe...
