Can you find the next number in the below sequence

 3 , 7 , 10 , 11 , 12 , 17 ?

Note: if already asked please comment below, as I've searched for this but not found on this site so that I posted it!

The next number is

20

This is because the sequence refers to numbers which:

Only contain the vowel 'e'
Eg. three, seven, etc.
Thirteen does not qualify because it contains an i, for example.

  • $\begingroup$ don't the numbers thirteen through nineteen contain 2 e's each, or more? $\endgroup$ – JLee May 8 '15 at 13:30
