Section 2.4, problem 5g.

Determine the first 10 terms of the sequence where the nth term is the number of letters in the English word for the index n.

I am not sure what this is asking for. Can anyone explain what this means and maybe how to arrive at the answer? The book's answer is: 3, 3, 5, 4, 4, 3, 5, 5, 4, 3.

Thanks,

Yvonne
