there. I came across this puzzle in a primary school booklet for selective high school exams in Australia. Please help me find out the next pattern to appear in the sequence, as shown in the picture below. Thank you very much!
I think the answer is
4th, because each of the three patterns in the question contains exactly four lines, and only the 4th option in the answer has four lines.
It could also be
3, since each figure must have an intersection of lines.
3. Because there are $0,1,2$ closed and equal shapes in each picture.
I would say:
4, because they are all composed from 4 straight lines.
