Yes, there is Bode's Law (or the Bode-Titius rule), but it's a purely
empirical relationship, and we have no real reason to think it
applies to other stellar systems.

But if you want to use it, it predicts that planets are found at
each value of 3n+4, where n = 0, 1, 2, ....  It works fairly well
for the Solar System if you count Mercury as planet 0, ...,
Ceres as planet 4, Jupiter as planet 5, etc.  Neptune however is
completely off from Planet 8, with a distance of 301 arbitrary units
instead of 388.  (Pluto, generally thought to be an escaped moon, is
at 394.)

The Bode's Law web page
(http://www.itsnet.com/home/bmager/public_html/pluto/bodeslaw.html)
says:

# The Titius-Bode Rule remains an interesting coincidence, for which
# no one has offered a satisfactory explanation.
