arithmetic sequences

等差数列, 算术序列

a sequence of numbers in which the difference between any two consecutive terms is constant

In the arithmetic sequence 2, 5, 8, 11, 14, ..., each term increases by 3, which is the common difference.
在等差数列 2、5、8、11、14、...中，每一项增加3，这是公差。
Arithmetic sequences are commonly used in finance to model situations where there is a constant increase or decrease in value over time.
算术序列常用于金融领域，以模拟价值随时间恒定增加或减少的情况。
In an arithmetic sequence, the difference between consecutive terms is always the same, regardless of the position of the terms.
在算术序列中，连续项之间的差异总是相同的，无论项的位置如何。
To determine if a sequence is arithmetic, we check if the difference between consecutive terms remains constant.
要确定是否存在等差数列，我们检查连续项之间的差是否保持不变。
