let's notate it with letters to I can notate it in this problem
the plus is P
the circle is C
the square is S
the smiley face is F (for face)
the triangle is T
in all, we see that:
circle can't be next to the smiley face or the triangle or the square so it must be at the end next to to the plus sign but we don't know if it is at the right end or the left (____P C or C P____)
plus is not next to smiley face or triangle, so it must be next to the square (___S P C or C P S___)
triangle is to the right of the square, so we have to choose the guess that has an empty space to the right of the square, so it has to be C P S T __
then the last shape is the smiley face which goes in the last space
so the order is C P S T F or circle, plus, square, triangle smiley face
