Sequence 和 Progression(AP) 意思基本上是一样的，都是 a sequence of numbers 。Series 指的是序列中每个元素的「和」(SUM)，比如Fourier series 傅里叶级数，等差数列的SUM叫做「算术级数」(arithmetic series),等比数列的叫做「几何级数」(geometrical progression).Sequence 、Progression序列 Seq...

An arithmetic series is the sum of the terms in an arithmetic sequence with a definite number of terms. Following is a simple formula for finding the sum:
An arithmetic series is the sum of the terms of an arithmetic sequence. A geometric series is the sum of the terms of a geometric sequence. There are other types of series, but you're unlikely to work with them much until you're in calculus. For now, you'll probably mostly work with...
