True or False.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~`

    In mathematics, a series is, informally speaking, the sum of the terms of an infinite sequence.  
    (Wikipedia, this article.)


False.


Classic counter-example is the harmonic sequence

1%2F2, 1%2F3, 1%2F4, . . . , 1%2Fn, . . . 

The sequence is converged (to zero), but the series is divergent.
