>>4870255to be honest I have no clue; I start to break things up to simpler steps and then try to reproduce them
for example: if you have those number rows
1 3 8 19 ....
i try to figure out what step was necessary to produce the outcome; in this case take the number before, multiply it by two and add a number which increases each step
(1*2+1=3 3*2+2=8 8*2+3=19 so on)
same goes with these pictures.
In the first row you can see that the first picture was mirrored vertical, next thing to notice that the diagonal symbols changed, sam goes for the symbol whch is nearest to the outside of the grid (sorry don't know the correct names in english and I am too lazy to look know, but I hope you get it)
the next row is pretty useless because the first pic is empty, so all mirror and changing rules have no effect on the last image of that row
now the last row, we are lucky because it also has an empty middle picture, so just let's try to reproduce the first row analog
mirror it vertical, change the diagonal symbols and at last the one that is nearest to the outer grid....and I think the correct answer would be E
I don't really think that you should train those things; don't know if it really would improve your logic/iq....
only tip I have as said, try to break it down to something that suits you; if you are bad with symbols, replace them with numbers or even colors; like every ace equals 1,spade 2 etc. and place them on a grid like in the test....maybe this helbs you more to see the pattern
