I need to rearrange this to form a logical sequence. One way is to just to trial and error, however since there are 5*4*3 ways this can rearrange, that is not efficient. Is there a way to number the elements so I can see a pattern clearly?

1OP: I've restored the original puzzle. If there's a valid reason for removing it (copyright issues? puzzle is in error?), please explain. – Brian Tung Jul 26 '16 at 16:57

Basic approach. Conceding that I haven't looked too closely at this, I would proceed as follows:
There are five shapes: circle, cross, diamond, heart, and slashed ring (the "don't" symbol). There are four textures: graph paper, polka-dotted, slashed, solid. Individually, for each of these properties—shape and texture—find the pattern followed by the figures, and then that will help you put these five triplets in a sequence so that the $15$ consecutive figures obey both patterns simultaneously.
For instance, for shape, a heart is always followed by what? Which is always followed by what? For texture, graph paper is always followed by what? And so on.

@anna_xox: I would say that this approach permits one to solve the puzzle in under $75$ seconds. However, I concede that you have to be pretty efficient about it: You can't spend too long thinking about the approach, and you might have to combine the steps into one process. – Brian Tung Jul 26 '16 at 16:58
