Question

choose the correct spanish word for the missing ordinal number:
3rd, 4th, ____, 6th, 7th
cuarto
primero
quinto

Explanation:

The sequence of ordinal numbers is 3rd, 4th, [missing], 6th, 7th, so the missing number is 5th. The Spanish word for 5th is "Quinto". "Cuarto" means 4th, and "Primero" means 1st, which do not fit the sequence.

Answer:

Quinto
