It is not a very good question, in my opinion

Re: IQ Test

I tend to agree.


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: IQ Test

hi HoaGio

How about 64 ?

Thus

Set n = 6 and f(n) = 64

hi zetafunc,

Not sure I have understood your solution.  Are you assuming the question was this:

What, in connection with this question, is the next number below?

4, 13, 19, 21, 29, ?

Re: IQ Test

Yes -- I even give the next two digits in my 'solution' (see the bolded letters).
