- Sounds like "show that 'pigs can fly' for all n such that n is in the set of
- positive integers". Though this does not say "prove", it is not sufficient to
- "show" it for a few integers. The reason for this is that "pigs could fly " for
- a lot positive integers, instances of which you would use by your reasoning, but
- fail for a few "integers" as well. In this case you certainly could not say that
- the original ascertion was true.
- The important bit here is the "for all integers".

- Hope this helps.
