Not really, starling. If the show doesn't have good ratings, why should you waste $6 million on 6 extra episodes, which you won't recover in terms of advertisements, toys, or DVD sales?

The average season length is traditionally 26 episodes (half a year's worth of eps if shown weekly). Justice League ran on a 26 episode season. Teen Titans ran on half of that - 13 episodes per season. Green Lantern: TAS is also a half-season, and so is ThunderCats 2011.

Young Justice: Invasion has an odd order number because Cartoon Network initially ordered ten episodes. They added another ten to their order, so we have twenty. Avatar: The Last Airbender is a special case, where we have three books of 20 episodes each, for a total of 61. Four short of the magic "65" syndication number, but that's not so important these days because of cable TV.
