Brain Game: Counting to 10

There has been heated debate recently over the value of shows like Sesame Street on the education of our youth. I was two years old when the show premiered back in 1969, and I know that it did a lot for me during my preschool days. One of the key things I learned was how to count, which gave me the ability to come up with today's Brain Game. (A hint? Probably.) Good luck!

The following series represents the numbers 1 through 10. What's the last number? 3, 3, 4, 6, 5, 4, 5, 4, 5, ?.

Here is the ANSWER.

THE ANSWER:

The last number is 4.

The series represents the number of letters in each number from 1-10, when spelled out in Spanish.

Uno (3), dos (3), tres (4), cuatro (6), cinco (5), seis (4), siete (5), ocho (4), nueve (5)... the next would be diez (4).
