I still like the multiplier of 9 rule. No matter what number you take, no matter how large or small, you can multiply it by 9 and the total sum of all those numbers will always equal 9 once you've added them together.
To wit:
Key in a random number: 7,545,154,872,145 x 9 = 67,906,393,849,305. Add each of those numbers up and you get 72, and 7 + 2 = 9.
Of course, this was demonstrated in a simpler manner by just taking things like 5 x 9 = 45, and 4 + 5 = 9. ;-)

Hmph. Why are all the numerical puzzles ridiculously easy while language ones take a bit of an effort? The calendar is biased, I tell ya. :)

Did you get the word puzzle?

So, you know, I do /know/ the answer...but it wouldn't be very fair for me to post it, now would it? @#;+)
Re:
That happens. But there will be other word puzzles I'm sure. ;)

All it is is the previous number multipled by 4. :-)
Re:
1^2 = 1
2^2 = 4
4^2 = 16
8^2 = 64
16^2 = 256
Perhaps a better puzzle would've been to find both explanations for the sequence. ;o)

Re:
If you double the root, because you're squaring, it's always going to be a four-fold increase.
I guessed 64 right away, and had to spend a minute thinking about /why/ it would be 64. There's just something about those powers of 2...
