(math) find a rule. writhe the rule as an equasion. use the equasion to extend the pattern.

What about the rule that dividing by 10 (or you can use multiplying by 10) moves the decimal point to the left?
Then the equation would be
100/10 = 10 or something similar. For multiplying, it would be
100 x 10 = 1000.
