What is the last word / Quel est le dernier mot?
(a) USE, FIX, QUIDS, CURT, EXIT, TUN, NORTH, EQUIP, AXIS, ? (b) EN, VOIE, TWIST, ENFERS, HIER, ONT, HUNE, VEXE, TOGE, ?
These are two separate questions.
From all the letters in part b) we can form the numbers from one to ten with some letters missing.
So we have EN VOIE TWIST ENFERS HIER ONT HUNE VEXE TOGE
minus ONE = VIE TWIST ENFERS HIER ONT HUNE VEXE TOGE
minus TWO = VIE IST ENFERS HIER NT HUNE VEXE TOGE
minus THREE = VIE IS ENFERS I NT HUN VEXE TOGE
minus FOUR = VIE IS ENES I NT HN VEXE TGE
minus FIVE = IS ENES I NT HN VEXE TGE -> missing F
minus SIX = ENES I NT HN VEE TGE
minus SEVEN = I NT HN EE TGE
minus EIGHT = N N E TE
minus NINE = TE -> missing I
minus TEN = TE -> missing N
so, I guess the missing word is FIN.
For part a)
In a similar manner removing one by one the French words for the numbers 1-10 we can find that we are missing the letters ned, but I guess the word in question is END, just so that it matches the French one.
USE FIX QUIDS CURT EXIT TUN NORTH EQUIP AXIS
minus UN = SE FIX QUIDS CURT EXIT TU NORTH EQUIP AXIS
minus DEUX = S FI QIS CURT EXIT TU NORTH EQUIP AXIS
minus TROIS = F QIS CU EXIT TU NRTH EQUIP AXIS
minus QUATRE = F IS C XI TU NTH EQUIP XIS
minus CINQ = F S XI TU TH EUIP XIS
minus SIX = F TU TH EUIP XIS
minus SEPT = F U TH UI XI
minus HUIT = F U XI
minus NEUF = XI -> missing NE
minus DIX -> missing D
So the missing word is END
