    I concur with the others. The correct answer is 6.

    Starting with n(1)=1, n(2)=2 and n(3)=3 we have n(i)=n(i-1)+n(i-3) for i=4 and upwards.

    n(5) must therefore be 6.

    well it could also be 5 because it is the next acending numeral and we were not instructed that it wasn't 5 in the question

    That's one of the reasons I dislike these types of problems. Who's to say that one answer is more valid than another? I think '5' and '6' are equally valid. Any number that conforms to a natural or mathematical pattern must be considered a solution.
