It is a question on a widely used IQ test. I always get all the answers, but this one I have never been able to solve. It is frustrating.

Problem with these is often no unique solution. Like 3,4,5,5,3,4,4,5,3,? : answer=3 for "one" ; get it? ten,nine,eight,seven,six,five,four,three,two,???=o ne=3(letters). Silly? Agree!
