There is a "pattern" relating to the size of a planet and the number of moons that it has. However, this cannot be used as a basis for determining how many moons a planet will have.
Jupiter is the largest planet and has the most moons. Saturn is the second largest and has the second most moons, Uranus is the third largest and has the third most moons. So it looks easy, but fails with the terrestrial planets.
Earth is the fifth largest but only has one moon, Venus the sixth largest doesn't have any moons. Whereas Mars has two moons but is the seventh largest.
