Well, I just figure out another puzzle type, let find out whether it could be the good series or not :P
This puzzle will provide several images, and these images compose a sequence with one or more properties. Please try to identify what the properties contained by this sequence, making images get grouped and ordered, and answer the missing one.
The answer should include an image, and a few reasons to illustrate why you pick the image. Note that the answer might not be unique, any image which meets the properties is correct(The green check may give to the first correct answer).
