A quick way of calculating the mean of an arithmetic sequence is to use the observation that, when the first and last terms are added, the sum is the same as when the second and next to last terms are added or the third and third to last terms. As a result, the sum of the sequen...

The sequence 2, 4, 6, 8,... is an arithmetic sequence. What is the common difference? A. 1 B. 2 C. 3 D. 4 相关知识点: 试题来源: 解析 B。解析:这个数列是等差数列,后一项减去前一项为定值,4-2=2,6-4=2,8-6=2,所以公差是 2。
How Geometric Sequences Work A geometric sequence is defined by its starting number a, the common factor r and the number of terms S. The corresponding general form of a geometric sequence is: \(a, ar, ar^2, ar^3, ... , ar^{S-1}\) ...
We define an arithmetic sequence as a sequence which has a common difference between all consecutive terms. This sequence is very useful in simulating certain scenarios in which there is a common difference.Answer and Explanation: The general formula for the arithmetic sequence is An=A1+(n−1)...
