    I think I'm onto the right way, but don't have it quite right yet: if there really is a function f(x), so that f(1) = 5, f(2) = 125, f(3) = 450 and f(4) = 1250 then this may help f(1) = 5 = 5^1 = 5^x f(2) = 125 = 5^3 = 5 ^ (x+1) = 5 * 5^x f(3) = 450 = 3.6 * 5^x f(4) = 1250 = 2 * 5^x At least I have found a way to show that all values are multiples of 5^x. If we bring this into the right form, we probably will quickly see the solution. Edit My current guess for f(5) would be around 5^x = 5^5 = 3125

      2795 :) f(x) = round(-179.9813978 + 307.4704136*x + -167.4867127*x*x + 44.99822836*x*x*x)

      50000000 :) algo:

      switch(in)
      {
      case 1:
      return 5;
      case 2:
      return 125;
      case 3:
      return 450;
      case 4:
      return 1250;
      default:
      return 50000000;
      }

            Neither. Used http://creativemachines.cornell.edu/eureqa[^] :) Trying to find an 'integer' solution though. But 4 points is a little too little to infer a pattern :(

              Do me one favor: Please try out the factors of 1, 5, 3.6 and 2 I got for X = 1, 2, 3 ,4 in this math software. What factor would be for x = 5?

                  input the points (1,1), (2,5), (3, 3.6) and (4, 2). I would like to know the value for (5, ?). I guessed that value to be 1 and then f(5) would be 3125. If your program can extrapolate a more precise value, we will se how good your brute force result and mine match.

                            As is often the case, there are an infinite number of correct answers. Examples: the cubic polynomial yields: 5 => 2785 one of the infinite number of fourth order polynomials yields: 5 => -1155 :)

                              Except that IQ tests don't usually require curve fitting software. There is a pattern here - that's the IQ bit. At the moment mine is 75.

                                      "1" was the logical answer, but, as it wasn't confirmed, I tried to examine this as a what's-next-in-series type of question. This just didn't make it, and, as it was presented as part of an IQ test, brute force methods are (should be) excluded. So I googled "1=5 2=25" and came up with: http://www.google.com/support/forum/p/blogger/thread?tid=2570697c07e3c6e3&hl=en[^] The poster of the question (a level seven whatever it is) congratulated other posters on their correct answer: 1 So why, exactly, were you annoyed?

                                          We clearly disagree on the attack strategy expected by the poser of the question (we never actually saw the original preposition). The IQ-test reference is the closest we have to determining expectations. I invoke Occam's razor .
