# What is the pattern to appear in the box?

I was puzzled by the pattern sequence in the following picture. What is the pattern to show up in the box? This is a question from a primary school workbook for selective high examinations in Sydney.

Thank you very much for your help!

• interestingly, there is a pattern of 4, 8, 12 in the amount of line segments that make up the figures. However none of the options have 16. – Legorhin Oct 3 '19 at 20:19
• Many thanks to everyone who has come in to join in the crack of the puzzle. All the thoughts put forward here are quite innovative in a way. Personally, I agree with the solution by @Lidaranis because that is the difference which is least arguable so far. Thank you again for your participation! – Michael May Oct 5 '19 at 11:43

2. There are no right angles in the sequence, and 2 is the only one without right angles.

• This is more convincing then @K Sharing's answer. – Duck Oct 4 '19 at 0:09
• Yes, agree that +1. And think that it's puzzle for primary school should not to be so complicated. – Conifers Oct 4 '19 at 2:52

The answer should be 2. It is basically w, x, y, and z. However, the letters are a bit modified.

• The third one hardly looks like y... – Prince Deepthinker Oct 3 '19 at 13:38
• look at the two diagonal lines – 昨晚忘記呼吸 Oct 3 '19 at 13:39
• Yeah I see it but it seems kinda weak. – Prince Deepthinker Oct 3 '19 at 13:40
• I was thinking the same but it doesnt seem convincing – Prince Deepthinker Oct 3 '19 at 13:41
• I mean you can kind of distort 4 to make it a z – Prince Deepthinker Oct 3 '19 at 13:48

I believe 2 since the (smaller) angle between any two intersecting lines should be the same in all figures (45 degrees).

• The third image in the sequence has 60-degree angles – Daniel Mathias Oct 3 '19 at 20:19
