I need to edit this code so the red dashed line can end up at R4 not R3 as in the following pictureenter image description here .



 documentclass[tikz,border=3.14mm]{standalone}
usetikzlibrary{positioning,calc,arrows.meta}
begin{document}
begin{tikzpicture}[bullet/.style={draw,circle,minimum width=3mm,inner
sep=0pt,
fill=cyan!50}]
node[bullet,label={[yshift=-2mm]below:$R_1$}] (R1){};
node[right=2cm of R1,bullet,label={[yshift=-2mm]below:$R_2$}] (R2){};
node[right=2cm of R2,yshift=6mm,bullet,label={[yshift=2mm]above:$R_3$}] (R3)
{};
node[right=2cm of R3,yshift=-6mm,bullet,label={[yshift=-2mm]below:$R_4$}]
(R4){};
node[right=2cm of R4,bullet,label={[yshift=-2mm]below:$R_5$}] (R5){};
foreach X [evaluate=X as Y using {int(X+1)}] in {1,...,4}
{draw[thick,-latex,cyan!50] (RX) -- (RY);}


draw[thick,red,{Circle}-latex,dashed] let p1=($(R2)-(R1)$), p2=($(R3)-
(R2)$),
n1={atan2(y1,x1)},n2={atan2(y2,x2)} in
([yshift=1mm]R1.north) to[out=n1,in=180,looseness=0.5]
([yshift=1mm]R2.north) to[out=0,in=n2-180,looseness=0.5]

          Instead of reconstructing the path of the red dotted arrow by clever calculations, you can use the preaction key which allows you to place the path in a temporary scope that you move vertically with transform canvas.



          To make it look prettier, I rounded the angles with the rounded key rounded corners=5pt.



          path[rounded corners=5pt,preaction={draw,red,thick,{Circle}-latex,
          ,transform canvas={yshift=3mm}}
          ] (R1.center)to(R2.center)to(R3.center)to(R4.center);


          path



          The result without the rounded corners:



          path-no

            Instead of reconstructing the path of the red dotted arrow by clever calculations, you can use the preaction key which allows you to place the path in a temporary scope that you move vertically with transform canvas.



            To make it look prettier, I rounded the angles with the rounded key rounded corners=5pt.



            path[rounded corners=5pt,preaction={draw,red,thick,{Circle}-latex,
            ,transform canvas={yshift=3mm}}
            ] (R1.center)to(R2.center)to(R3.center)to(R4.center);


            path



            The result without the rounded corners:



            path-no

                To make it look prettier, I rounded the angles with the rounded key rounded corners=5pt.



                path[rounded corners=5pt,preaction={draw,red,thick,{Circle}-latex,
                ,transform canvas={yshift=3mm}}
                ] (R1.center)to(R2.center)to(R3.center)to(R4.center);


                path



                The result without the rounded corners:



                path-no



                documentclass[tikz,border=3.14mm]{standalone}
                usetikzlibrary{positioning,calc,arrows.meta}
                begin{document}
                begin{tikzpicture}[bullet/.style={draw,circle,minimum width=3mm,inner
                sep=0pt,
                fill=cyan!50}]
                node[bullet,label={[yshift=-2mm]below:$R_1$}] (R1){};
                node[right=2cm of R1,bullet,label={[yshift=-2mm]below:$R_2$}] (R2){};
                node[right=2cm of R2,yshift=6mm,bullet,label={[yshift=2mm]above:$R_3$}] (R3)
                {};
                node[right=2cm of R3,yshift=-6mm,bullet,label={[yshift=-2mm]below:$R_4$}]
                (R4){};
                node[right=2cm of R4,bullet,label={[yshift=-2mm]below:$R_5$}] (R5){};
                foreach X [evaluate=X as Y using {int(X+1)}] in {1,...,4}
                {draw[thick,-latex,cyan!50] (RX) -- (RY);}

                path[rounded corners=5pt,preaction={draw,red,thick,{Circle}-latex,
                ,transform canvas={yshift=3mm}}
                ] (R1.center)to(R2.center)to(R3.center)to(R4.center);
                end{tikzpicture}
                end{document}
