Sequence convergence
converges if for some limit ; otherwise it diverges.
Examples
Examples grounded in the definition:
-
converges to : given , the Axiom of Archimedes supplies , and then for all .
-
The sequence defined by for even and for odd converges to by the same choice of , treating the two parities separately.
-
converges to , since .
-
The alternating sequence diverges: with , no tail can stay within of any proposed limit, since . Divergence does not require the terms to tend to infinity.
