WebThe summation formula is: ∑ i = 1 n a i = a ( 1 − r n) ( 1 − r) Rearranging the terms of the series into the usual "descending order" for polynomials, we get a series expansion of: a r n – 1 + a r n – 2 + … + a r 3 + a r 2 + a r + a A basic property of polynomials is that if you divide x n – 1 by x – 1, you'll get: WebHence, we have the sum formula for the infinite geometric series as shown below. S ∞ = a 1 – r S ∞: Infinite series’ sum a: First term r: Common ratio: − 1 < r < 1 We now have the two essential sum formulas for the geometric series. It’s now time that we learn how to apply these two formulas when given a geometric series.
Web18 okt. 2024 · Ans: A geometric series is a series where each term is obtained by multiplying or dividing the previous term by a constant number, called the common ratio. And, the sum of the geometric series means the sum of a finite number of terms of the geometric series. Example: Let us consider the series \ (27,\,18,\,12,\,…\)
