Hi Guys,
Whats the next picture in the series?

Its C.

E

I agree.

Using standard quadrants:

2: q II and III are mirrored vertically
3: q III and IV are mirrored horizontally
4: q IV and I are mirrored vertically
5: q I and II are mirrored horizontally

E: as in 2: q II and III are mirrored vertically

Edit: I see that embedded linx are not 'spoiled'

Here's how I see it, you should rotate the white triangles in each of the quadrants clockwise a certain number of times, as follows:

1^st q: 0 0 2 1 0
2^ndq: 1 0 0 3 3
3^rd q: 3 3 0 0 1
4^th q: 0 1 2 0 0

I personally think its C too, so here's my logic:

For the first and second pictures, the 4th and 1st quadrant remains the same,
For the second and third pictures, the 1st and 4th quadrants remains the same,
For the third and fourth pictures, the 4th and 3rd quadrants remains the same,
For the forth and fifth pictures, the 3rd and 2nd quadrants remain the same,

Hence the fifth and sixth pictures, the 2nd and 1st quadrants remain the same

For the first and second pictures, the 4th and 3rd quadrants swap positions.
For the third and fourth pictures, the 1st and 4th quadrants swap positions.

Hence for the fifth and sixth pictures, the 4th and 3rd quadrants swap positions.

Answer is C.

Each column represents the number of rotations occurred by the white triangle in each of these quadrants [4 times precisely], and as a result it form a centrosymmetric matrix.

wow ..thats an interesting way of looking at the problem

 

[drizzle]

Yeah, complicating it to solve it.

 

[Borek]

I see C.

Each time half is not modified, in other half pieces are exchanged. Not modified half is rotated CCW, it starts with right half.

 

[drizzle]

Correct, and simple... *sigh*

 

[Borek]

Yep. But I found it at third attempt

 

[OmCheeto]

C.

Convert position in each quadrant to a numerical value: #2 is Rosetta stone: 0, 1, 2, 3

Original sequence:
1: 1023
2: 0123
3: 3120
4: 3102
5: 3012

Possible solutions:
a: 2300
b: 2310
c: 0312
d: 3221
e: 1212

no position is duplicated(eliminating a, d, & e), and only adjacent(circularly) shapes swap(eliminating b)
