Definition

The series defined as:

$\displaystyle \sum_{n \mathop = 1}^\infty \frac 1 n = 1 + \frac 1 2 + \frac 1 3 + \frac 1 4 + \cdots$

is known as the harmonic series.


General Harmonic Series

Let $\sequence {x_n}$ be a sequence of numbers such that $\sequence {\size {x_n} }$ is a harmonic sequence.


Then the series defined as:

$\displaystyle \sum_{n \mathop = 1}^\infty x_n$

is a harmonic series.
