The next number would be one octodecillion and one, or 1 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 001 (U.S. and scientific. The British and other country version would be a one followed by 107 zeros, followed by a one.) If you meant, what series of numbers comes after octodecillions, it's novemdecillions.
3 x 109 = 3 000 000 000 (3 x 10)9 = 19 683 000 000 000
