I haven't seen the increase by five, but by twos when the odds/evens are separated across the street from each other. 101's next door neighbor is 103 while 102 is across the street next door to 104.

That's what the European sequential method is. We have that in Australia, odd numbers are on the left, even on the right.

...Although sometimes it's the opposite, from before it was standardised.

		Most streets in the US are the same - there is an odd and even side of the road. Most are as said elsewhere also your house number is distance from the corner (most often in units of 100 feet) - I've seen half numbers before when houses when doors are close together, but normally they round. However every development is different. The rules might be set by the city, but they change often enough that we can call this per development, others is really is the developer decides. Even where the city sets the rules, a "small fee" lets you choose your street name and address - which is why for most large companies their headquarters is "1 [company name] drive". Still the observation that in the US address are distance to corner with and even and odd size applies to the vast majority.

		Depends on from where you enter the street, does it not? (I kid, I know what you mean ;))
