Definition:Limit of Sequence (Number Field)

Definition
As:
 * The set of rational numbers $\Q$ under the usual metric forms a metric space
 * The real number line $\R$ under the usual metric forms a metric space
 * The complex plane $\C$ under the usual metric forms a metric space

the definition of the limit of a sequence in a metric space holds for sequences in the standard number fields $\Q$, $\R$ and $\C$.
