1, 0, 3, 11, 15... What are the next two numbers in this series?

13, 17. The series begins with the first number to have the least amount of letters in its name, starting with zero. (Ex. `1` has 3 letters in `one`, `0` has 4 letters in `zero`, `3` has 5 letters in `three`, `11` is the first number to have 6 letters in its name, 15 is the first to have 7 letters in its name...and so on). The series continues up to number 9. `13` is the first to have 8 letters and `17` is the first to have 9 letters.Hide Answer Show Answer
