(A) 1/2 (B)1 (C) 3/2 (D)2 (E)5/2 相关知识点: 试题来源: 解析选A 1/2 :此无限等比数列求和公式为S∞=a1/(1-q) ,a1是首项,q是公比 所以代入数值后得 S∞=(1/4)/(1-1/2)=1/2 即为此等比数列的总和. 故选A 1/2 【此题的英文翻译】无穷等比数列 1/4+1/8+1/16+1/32+...
let’s take a quick detour to talk about what I consider to be a rather beautiful area of math—sequences and series. Today, we’ll discuss a particular type of sequence
The film The Man Who Knew Infinity tells the gripping story of Srinivasa Ramanujan, an exceptionally talented, self-taught Indian mathematician. While in India, he was able to develop his own ideas on summing geometric and arithmetic series without any f
In particular, from the triangle inequality and geometric series By weak compactness, some subsequence of the , converge to some limiting random variables , and by some simple continuity properties of entropic Ruzsa distance, we conclude that and Theorem 2 then follows from the “100% inverse...
解析 Sample answer: The graph of S_n seems to be approaching 1. This makes sense because ∑limits_(k=1)^∞( 12)^k is a defined infinite geometricseries with S=(12)(1-( 12))=1. 结果一 题目 【题目】For the following exercises, use the geometricseis ∑_(k=1)^∞(1/2)^kW...
Looking forward to a career in Data Analytics? Check out the Data Analytics Course and get certified today. Conclusion With this, you have come to an end of this Arithmetic and Geometric Progression tutorial. You have learned how to calculate the nth term of any series and also the sum of...
The geometric mean is the average of a set of values calculated using the products of the terms. The geometric mean is most appropriate for series that exhibit serial correlation—especially investment portfolios. Most returns in finance are correlated, including yields on bonds, stock returns, and...
disallowed. Using the harmonic mean allows a more significant weighting to be given to smaller values in the series, and it can also be calculated for a series that includes negative values. In comparison with the arithmetic mean and geometric mean, the harmonic mean generates a straighter curve...
To calculate the geometric mean, multiply all the values in a dataset, then take the root of the sum equal to the number of values within that dataset. Eliana Rodgers / Investopedia Arithmetic Mean The arithmetic mean is the simple average or sum of a series of numbers divided by the count...
