4 Is Cosmic

1 is 3,
3 is 5,
5 is 4,
4 is cosmic.

What is 6? And what is meant by cosmic?

6 is 3 of course. Because six has three letters.

One = three letters
Three = five letters
Five = four letters
Four = four letters

Cosmic is a number that has the same number of letters as the value. Four is the only number I’m aware of that has this property.

A Third of the Way But Only Halfway There

You’ve traveled a third of the way, yet you’re only halfway there.

Where are you going?

Hint: The answer applies in the US but not in Europe.

You’re in a build headed to the fourth floor. When you reach the second floor, you’ve gone one floor and have two more floors left, so you’re 1/3 of the way. But at the same time, you’re on the 2nd floor and have two more floors to get to the 4th floor, thus you’re halfway there.

This doesn’t work in Europe, because they typically refer to the “first floor” as the ground floor, and the first floor is one story up.
