but it’s really pretty simple. An arithmetic sequence is a sequence of numbers where the difference between any two successive elements is always the same constant value. For example, the sequence of years since the start of the new millennium is an arithmetic...
In algebra, sequences of numbers are valuable for studying what happens as something keeps getting larger or smaller. An arithmetic sequence is defined by the common difference, which is the difference between one number and the next one in the sequence. For arithmetic sequences, this difference ...
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 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。

When calculating math problems it is necessary to follow the correctorder of operations, meaning the specific order in which different operations should be completed. To do this, each operation must be grouped and completed at the correct time. What is grouping in math and what are groupingsymbol...
