Definition

In mathematics, an arithmetic series is the sum of the components of an arithmetic progression. Mathematics is the study of quantity, structure, space and change. ... In mathematics, an arithmetic progression is a sequence of numbers such that the difference of any two successive members of the sequence is a constant. ...


Formulas

Formulas for arithmetic series usually use Sn to represent the sum of the first n terms of an arithmetic progression, an for the nth term of the arithmetic progression, and d for the common difference between the terms of the arithmetic progression. The formula to determine the sum of the first n terms of an arithmetic progression is:

An often-told story is that Gauss discovered this formula when his third grade teacher asked the class to find the sum of the first 100 numbers, and he instantly computed the answer (5050). Johann Carl Friedrich Gauss Johann Carl Friedrich Gauss (Gauß) (April 30, 1777 – February 23, 1855) was a German mathematician and scientist who contributed significantly to many fields, including number theory, analysis, differential geometry, geodesy, magnetism, astronomy and optics. ...

In mathematics, an arithmetic series is the sum of the components of an arithmetic progression.
Series may be finite, or infinite; in the first case they may be handled with elementary algebra, but infinite series require tools from mathematical analysis if they are to be applied in anything more than a tentative way.
Series for the expansion of sines and cosines, of multiple arcs in powers of the sine and cosine of the arc had been treated by Jakob Bernoulli (1702) and his brother Johann Bernoulli (1701) and still earlier by Viète.
Draw Sizer - Arithmetic Progression (346 words)
This utility employs arithmetic progression to compute drawer face heights by progressively adding a fixed increment to successive drawers beginning with the top drawer.
With arithmetic progression, the heights of successive drawer faces differ by a constant amount or "increment".
Arithmetic progression is fairly straightforward, especially when you already have values in mind for the height of the top drawer, the number of drawers, and the height increment.
