I'm want to put suspension points as in the picture above. What should I add to the code below?



documentclass[12pt]{article}    

usepackage{tikz}  

begin{document}  

begin{tikzpicture}[roundnode/.style={circle, fill=black!70, inner sep=0pt, minimum size=1.5mm}]



    node[roundnode,label=right:{$u^{}_1$}] at (1,0) (u1) {};

    node[roundnode,label=above right:{$u^{}_2$}] at (0.78539816339,0.70710678118) (u2) {};

    node[roundnode,label=:{$u^{}_3$}] at (0,1) (u3) {};

    node[roundnode,label=above left:{$u^{}_4$}] at (-0.78539816339,0.70710678118) (u4) {};

    node[roundnode,label=left:{$u^{}_5$}] at (-1,0) (u5) {};

    node[roundnode,label=left:{$u^{}_6$}] at (-0.78539816339,-0.70710678118) (u6) {};

    node[roundnode,label=below:{$u^{}_7$}] at (0,-1) (u7) {};

    node[roundnode,label=below right:{$u^{}_n$}] at (0.78539816339,-0.70710678118) (un) {};



    draw[-] (un) -- (u1) -- (u2) -- (u3) -- (u4) -- (u5) -- (u6) -- (u7);

end{tikzpicture}  

end{document}

    Welcome to TeX - LaTeX! By "suspension points" do you mean the dotted line? If so then draw[dotted] or draw[loosely dotted] is probably what you are looking for. You can add thick or similar to get larger dots.

Slightly more complicated than nidhin's solution, add usetikzlibrary{calc} and use 



foreach i in {0.25,0.5,0.75}

    fill ($(un)!i!(u7)$) circle[radius=1pt];


enter image description here



documentclass[12pt]{article}    

usepackage{tikz}

usetikzlibrary{calc}

begin{document}  

begin{tikzpicture}[roundnode/.style={circle, fill=black!70, inner sep=0pt, minimum size=1.5mm}]



    node[roundnode,label=right:{$u^{}_1$}] at (1,0) (u1) {};

    node[roundnode,label=above right:{$u^{}_2$}] at (0.78539816339,0.70710678118) (u2) {};

    node[roundnode,label=:{$u^{}_3$}] at (0,1) (u3) {};

    node[roundnode,label=above left:{$u^{}_4$}] at (-0.78539816339,0.70710678118) (u4) {};

    node[roundnode,label=below right:{$u^{}_n$}] at (0.78539816339,-0.70710678118) (un) {};



    draw[-] (un) -- (u1) -- (u2) -- (u3) -- (u4) -- (u5) -- (u6) -- (u7);

    Drawing dotted lines is one way to produce this picture. (mentioned is comments by Andrew Swann also.). IS this okay for you?
