In practice, the asymptotic rate and order of convergence of a sequence of iterates or of approximations provide useful insights when using iterative methods and discretization methods for calculating numerical approximations. Strictly speaking, however, the asymptotic behavior of a sequence does not

Asymptotic rates and orders of convergence have particular importance both in practical numerics and in formal proof, and they are the primary focus of this article. In practical numerics, asymptotic rates and orders of convergence follow two common conventions for two types of sequences: the first

The definitions of Q-convergence rates have a shortcoming in that they do not naturally capture the convergence behavior of sequences that do converge, but do not converge with an asymptotically constant rate with every step, so that the Q-convergence limit does not exist. One class of examples is

Where greater methodological precision is required, these rates and orders of convergence are known specifically as the rates and orders of Q-convergence, short for quotient-convergence, since the limit in question is a quotient of error terms. Sequences with larger orders

A practical method to calculate the order of convergence for a sequence generated by a fixed point iteration is to calculate the following sequence, which converges to the order

In such cases, a closely related but more technical definition of rate of convergence called R-convergence is more appropriate; the "R-" prefix stands for "root." A sequence
