Divergent geometric series information


In mathematics, an infinite geometric series of the form

is divergent if and only if | r | ≥ 1. Methods for summation of divergent series are sometimes useful, and usually evaluate divergent geometric series to a sum that agrees with the formula for the convergent case

This is true of any summation method that possesses the properties of regularity, linearity, and stability.
