    How about this infinite product here? (99/10)*(111/110)*(1111/1110)*(11111/11110)*... The partial products are: 9.9 9.99 9.999 9.9999 and so on... The product

      How about this infinite product here?

      (99/10)*(111/110)*(1111/1110)*(11111/11110)*...

      The partial products are:
      9.9
      9.99
      9.999
      9.9999
      and so on...

      The product quite obviously converges to an even number (10), but all of
      the numerators are odd and all of the denominators are even. Even and
      odd really have no meaning when it comes to infinity and limits. As
      this example shows, a series of partial products, all of which have
      odd numerator and even denominator, can converge to not only a rational
      number, but an even integer.
