f:N→N f(n+1)>f(f(n)) then f(2009)=?

It seems the answer would be 2010. However, please check the question.

It looks like f(x)=x satisfies the inequality

as x+1 > x

so for f(x)=x , f(2009) = 2009

However, I feel that there is some ambiguity in question

the answer is most probably 2010.check the question though,somethin is missin
