Blast into Math! Analatic nummer theora: ants, ghosts and giants

5. Next, the ghost number scares all the surviving ants (terms) under its sheet, which only

stretches from L − to L + . This is the statement

|x n − L| <,

because |x n − L| is the distance between x n and L on the number line. This distance must
be less than , which means that:

and L + .
the surviving terms in the sequence are all trapped between L − to L + .L − to
