60?
2x12=24
24+12=36
3x12=36
36+12=48
Then
5x12=60
60+12=72
Of course this may all be rubbish
2x12=24
24+12=36
3x12=36
36+12=48
Then
5x12=60
60+12=72
Of course this may all be rubbish

Strangely if you just take 12 from the number on the right you get the same

I believe you need to use the outside numbers to arrive at the middle number so:2 [24] 36 3 [36] 48
5 [?] 72
Find the missing number!!!
(2 x 36) / (2 + 1) = 24
(3 x 48) / (3 + 1) = 36
(5 X 72) / (5 + 1) = 60

I'm reading these forums with interest to see what sort of things get asked in these tests, and I've never come across these types of problems before.
If the three numbers can be termed A and C
I take it that what the kid needs to do is (in a roundabout way) generate a method for caluclating B that uses A and C using +, -, / and x and any constants they require?
Thus for the question above we have
2 [24] 36
3 [36] 48 and
5 [x] 72
I presume they have to show working too?
Would it be ok to show it as:
b=((A+1)x12)-12
Sorry, I'm new to this!

You don't need to show how you got there - but you should be looking for an answer that uses both A and CWould it be ok to show it as:
b=((A+1)x12)-12

Hi, no they just have to mark the right box. Of course they have to be able to work out the answer in order to that so they do need to be familiar with the question type and able to look at numbers logically. Lots of practice ahead of time will help.
Everyone is a genius, but if you judge a fish by its ability to climb a tree, it will think it is stupid.

I actually ended up with two equations:
c=(a+1)x12 and
b = c-12
I just substituted to get to b=((a+1)x12)-12, but I used a and c to get there.
