hi there, anybody can help solve this? , TQ.
4--------- 2--------- 8
17-------- 54 --------92
298 ------756------- 644
2134 ----5196------ 8843
The question is: Out of the 12 numbers in the 3x4 box (the 12 numbers each in one square) up there, Which 2 numbers do not belong up there?
It was just a question from my son's IQ Maths which he asked me.
As i am not sure if my answer is correct i ask for opinion here.
However, I cannot fathom how there can be 66 answers all with logical reasoning.
The point that Plato is making is that we can potentially pick any two of the numbers and find some sort of reasoning to say they are different from the rest. It is a similar concept to having a list of numbers, say 1, 2, 4, 5, 7 and ask what the next number is. If you are sufficiently clever you can argue that any number is the next in the series.Originally Posted by labrador007
So there really is no "right" or "wrong" answer to your question. The question itself is flawed.

for some lunatic reason i thought 17, 8843 on the grounds that they were the only prime numbers before noticing that they were also the only odd numbers.
Im not a psychiatrist but i think you need to be careful before discarding this sort of thing as a rubbish test/stupid question. I agree that any sufficiently clever person could come up with a justification for any of the pairs, and so the question isn't perfect (especially if only 1 answer will get any credit).
However the purpose of IQ testing is to predict certain traits (i dont know what they are, but anyway), so the only issue of relevance to the tester is whether or not there is a correlation between certain answers and the traits being tested for. If its a professional test i would assume they tested for that correlation when designing the answer key.
There are only two that are divisible by 14.
There are only two that are divisible by 12.
There are only two that are divisible by 9.
There are only two that are divisible by 7 (the same two as divisible by 14).
There are only two semi-primes.
There are only two with four neighbours.
etc

Exactly. SpringFan25 has overlooked the number 2. May be he did this because those are the only two odd numbers and it is only the odd numbers which can be prime (apart from 2,of course). So I think may be he too first noticed that those numbers were odd....gusess whatsoever.....
8843 isn't prime, so my post was a bit of a mess. What i meant to say was i thought about "2,17" as prime before noticing "17, 8843" as odd. Which i think is pretty lunatic of me...
However the purpose of my post was not to say "hey, this is the answer" it was that having many answers doesn't make it a bad question, provided the answer key has been done sensibly, to give credit to those answers which correlate best to what IQ tests are looking for.
Another simple pattern,
all depending on the level of the child being tested,
is that...
the numbers are increasing from the previous one
except for "2" and "644".
If it weren't for those,
the first line could be increasing in units,
the 2nd line increasing in tens,
the third line increasing in hundreds,
the fourth line increasing in thousands,
or just take the sequence beginning with 4 and ending with 8843.
