Arithmetic Mean An arithmetic sequence has a corresponding series that adds all the terms of the sequence. When the terms are added and the sum is divided by the number of terms, the result is the arithmetic mea
The Fibonacci sequence is a famous mathematical sequence where each number is the sum of the two preceding ones. People claim there are many special properties about the numerical sequence, such as the fact that it is “nature’s secret code” for building perfect structures, like theGreat Pyra...
该算数数列的第100个数是:1,5,9,13,17,21,25,⋯? 要从算术序列的第一项到第100项,我们必须加上99倍的公差.第一项为1,公差为5−1=9−5=13−9=⋯=4,因此第100项为1+4(99)=397. 故选A.结果一 题目 What is the 100th number in the arithmetic sequence: 1,5,9,13,17,21,25,?

The first two equations are essentially stating that the term in the first position equals 0 and the term in the second position equals 1. The third equation is a recursive formula, which means that each number of the sequence is defined by using the preceding numbers. For example, to defin...
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。
