Spellings used for French numbers: zero, un, deux, trois, quatre, cinq, six, sept, huit, neuf, dix, onze, douze, treize, quatorze, quinze, seize, dix-sept, dix-huit, dix-neuf, vingt, vingt et un, vingt-deux, vingt-trois, vingt-quatre, vingt-cinq.
The numbers 18 and 22-25 do not occur in the sequence. - David Applegate, Sep 24 2007
There appears to be no analog in Spanish. (The requirement is that the difference between the ranks of the first two letters in the word for the number n should equal n.) - David Applegate, Sep 24 2007. There exists such a sequence (namely, 12, 13, 2, 16, 2, 14, 2, 2, 1...) if (as is standard) letter 'ñ' is granted an alphabet position, whereas digraphs such as 'll' are not. - Álvar Ibeas, Sep 18 2020

Examples

			The sequence begins Quatre, vingt, dix-neuf, deux, treize, ...

The first English names of the sequence are:
FIVE, TEN, TWENTY, EIGHT, ONE HUNDRED, FOUR, SEVEN, TWELVE, THIRTEEN, ONE, NINETEEN, TWENTY-SIX, EIGHTEEN, SIXTY-EIGHT, SIXTY-NINE, TWO, SEVENTY-ONE, THIRTY-EIGHT, SIX, FOURTEEN, ELEVEN, FORTY-FOUR, NINE, THIRTY, SEVENTEEN, TWENTY-THREE, TWENTY-FOUR, TWENTY-FIVE, THIRTY-TWO, TWENTY-ONE, TWENTY-EIGHT...
If we now take the 5th letter of the above English sequence (T), the 10th (E) and the 20th (N) we spell T.E.N. and 10 is the double of a(1) = 5. We then take the 8th letter of the sequence (T), the 100th (W), the 4th (E), the 7th (N), the 12th (T), the 13th (Y) to form T.W.E.N.T.Y. and 20 is the double of a(2) = 10. Etc.
