Annoying IQ Test
-
Someone ask me this IQ Test and I got really annoyed when I found out the answer. Here it is: If 1 = 5, and 2 = 125, and 3 = 450, and 4 = 1250, then 5 = ?

Thought the same, but it probably should read more like f(1) = 5, f(2) = 125 ... and in the end we are supposed to figure out what exactly f is and calculate f(5)

If that's really an equivalence on integers, I'm pretty sure it can be proven that x = y for all x and y that are integers. edit: actually, I'm not sure anymore. If this equivalence is assumed, do the usual integer axioms still hold? Is math still possible?

Normally an IQ will provide you a multiple choice of answers. Else I will be playing my
leppie's functioncard! -

Why not 50000000? :-D

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

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

I went brute force ;p See my latest answer.

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?

Not quite sure how to input that into the software :(

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.
