Divergent

Pronunciation: /dɪˈvɜr.dʒənt/ Explain

Most authors divide infinite series into two classes: convergent and divergent. A series is convergent if the sum of the series approaches a finite limit.

A series is divergent if it is not convergent.

Other authors divide infinite series into three classes: convergent, divergent and oscillating. An infinite series is convergent if it approaches a finite value, divergent if it approaches an infinite value^[2], and oscillating if it does not approach any value.

An object that is divergent is said to diverge.

An example of an infinite series that diverges is the harmonic series:
