Which sequence is neither arithmetic nor geometric? A. 1, 2, 3, 4,... B. 2, 4, 6, 8,... C. 1, 4, 9, 16,... D. 3, 6, 9, 12,... 相关知识点: 试题来源: 解析 C。解析:A、B、D 分别是公差为 1、2、3 的等差数列,而 C 数列不是等差数列也不是等比数列。
In mathematics, we have two important types of sequences: Arithmetic sequence and Geometric sequence. In arithmetic sequence, the difference between the two terms i.e. any term of sequence and its previous term is the same whereas, in a geometric sequence, the ratio of ...
If the sum of the first n terms of a sequence is 6n2−n, which of the following is/are true?( ) Ⅰ. 22 is a term of the sequence. Ⅱ. The 1st term of the sequence is 5. Ⅲ. The sequence is a geometric sequence. 若某数列的首n项之和为6n2−n,则下列何者正确?( ) Ⅰ.22...
(minimum variance unbiased estimate), the geometric moving average and the arithmetic moving average. The coefficients of the m.v.u.e. depend on c = σ2 2/σ2 1 and n, the number of periods of time at which measurements have been made. The inefficiencies caused by using the geometric ...

摘要: We prove that for any partition of a set which contains an infinite arithmetic (respectively geometric) progression into two disjoint subsets, at least one of these subsets contains an infinite number of triplets such that each triplet is an arithmetic (respectively geometric) progression....
