sequence of numbers with constant differences between consecutive numbers
This article uses too much jargon, which needs explaining or simplifying. (October 2022)
In mathematics, an arithmetic progression, or arithmetic sequence, is a sequence with the property that the difference between the two terms which follow one another is constant. This is different from a geometric progression, where the ratio of change between two terms is constant.
If the initial term of an arithmetic progression is and the common difference of successive members is , then the -th term of the sequence () is given by:
A finite portion of an arithmetic progression is called a finite arithmetic progression and sometimes just called an arithmetic progression. The sum of a finite arithmetic progression is called an arithmetic series.
