CONVERGING or CONVERGENT Lines, in Geometry, are such as continually approach nearer to one another, or whose distances become still less and less. These are opposed to divergent lines, the distances of which become continually greater. Lines which converge one way diverge the other.

CONVERGING Series, in Mathematics, are series of which each succeeding term is smaller than the preceding, and which consequently tend to a certain limit: in opposition to diverging series, in which the terms gradually increase. See SERIES.
