### Hint

4 hints coming your way:Does the title help at all?

You may need google.

If you want, you could try to figure out the next 17 numbers.

The first one may not be an 11, but a 1 and a 1.

### Answer

13The numbers represent how many dots and dashes (respectively) are in each Morse code letter of the alphabet. So A = dot-dash (1 dot, 1 dash = 11), B = dash-dot-dot-dot (3 dots, 1 dash = 31), etc. I ended on I = dot-dot (2 dots, no dashes = 20) so next is J = dot-dash-dash-dash (1 dot, 3 dashes = 13). Here is the rest of the series if you want it:

12, 31, 02, 11, 03, 22, 13, 21, 30, 01, 21, 31, 12, 22, 13, 22
