|=|, |=|, -|, |=, |=, |-|, =|, ..., ...
What are the last two symbols in this sequence?
Sorry for being so unclear. There's how I'd draw those symbols:
The pic is just for analogy, you still should end the original sequence, not this one.
Duplication (first and second, forth and fifth) is not something you should look at in first place (not the primary logic).
You meet these symbols in everyday life.
Try to draw all the symbols on the paper, without spaces inside each symbol (i.e., each symbol with one solid line)
