The answer I found is
18, 11, 15, 14, 19, 17, 16, _10_, _13_, _12_, _20_
and this is how I found it:
I wrote the numbers in letters like this:
eighteen
eleven
fifteen
fourteen
nineteen
seventeen
sixteen
and I saw that they are in alphabetical order and that the missing
numbers fit in alphabetical order after that:
ten
thirteen
twelve
twenty.

to go from 18 to 15 subtract 3
to go from15 to 19 add 4
to go from 19 to 16 subtract 3
to go from 16 to 20 add 4
( the pattern is subtract 3 plus 4 for every other number)
to go from 11 to 14 add 3
to go from 14 to 17 add 3
to go from 17 to 20 add 3
(the pattern is add 3 for the other numbers)

Spenser Smith from Oakville Canada.
This is my answer to #405. 10, 12, 13, 20
I added up the digits in each number. Then I looked for the difference
between each number in order. The sum of the digits plus or minus the
difference between each number gave me the next number. For example I
added one plus 6 in 16 to get 7. Then I took 6 away to get one plus zero
in the TEN. This is hard to explain!
