Base Three

Computers are designed around the fact that it is easy to store and manipulate bits with components that have two states (e.g. 1 or 0, on or off, high voltage or low voltage). It is just possible that at some point it will become more efficient to work with components that naturally have three states. Then computers will work base three (or ternary). If that happens then the sequence of numbers starting with three and continuing by multiplying by three to get bigger and bigger numbers will become very important to computer scientists:
3 -> 9 -> 27 -> 81 -> etc.
Continue this sequence as far as you can mentally, or as far as you have time on paper.
