[AccessD] OT: Friday entertainment

Gustav,

One may guess the basis of notation isn't decimal and try the most obvious
5, 7 and 16 as a notation basis and convert the sequence to the numbers
with decimal notation basis - then they will get:

        10 11 12 13 14  20  22  31

5:     5     6   7    8   9  10  12  16
7:     7     8   9   10 11 14 16  22
16:  16  17 18  19 20 32 34  49

No clue :(

Stupid idea: total quantity of any used digit should be even or odd
and the answer should be greater than the last number in the sequence and
the answer should have two digits?:

Given:
=====
  0 -> 2
  1 -> 7
  2 -> 4
  3 -> 2
  4 -> 1

With one additional number with two digits  the quantity of every used digit
can be made even. It can't be made odd.

Target:
=====
  0 -> 2
  1 -> 8
  2 -> 4
  3 -> 2
  4 -> 2

Answer: 41?

It doesn't look like this answer deserve a a tasty chocolate but anyway for
others to look for the right answer in other areas....

P.S. My Friday puzzle to you Gustav :)

10 11 12 13 14  20  22  (?) 31
