Answer:
10,13,3,12,2 (I had this question in my class once:))
Step-by-step explanation:
This question does not follow any mathematical rule or sequence, it is in the alphabetical order as numbers spelled.
Eight, eighteen, eleven, fifteen, five, four, fourteen, nine, nineteen , one, seventeen, six, sixteen, and so on, and you can see numbers are between 1 to 19.
The order is meaningless as numbers but, when you treat them as words it gets meaningful as words pattern becomes clear.
To complete the list think of 2, 3, 10, 12, 13 as two, three, ten, twelve and thirteen which would be written alphabetically as ten, thirteen, three, twelve, two.
So the remaining numbers should be written in that order: 10,13,3,12,2.
