I am trying to draw a tree using tikzpicture like this:

begin{tikzpicture}

    tikzstyle{node}=[circle, fill=blue!25, minimum size=0.1 cm];

    foreach ilayer in {0,...,3} {

        tikzmath {nnodes = 3 ^ ilayer; }

        tikzmath {leftnum = 1 - floor(nnodes / 2) - 1; }

        tikzmath {rightnum = nnodes - floor(nnodes / 2) - 1; }

        foreach isibling in {leftnum,...,rightnum} {                

            tikzmath {d = 3 ^ (- ilayer) * 15; }

            tikzmath {x = isibling * d; }

            tikzmath {y = - ilayer * 2; }

            node[node] (node_ilayer_isibling) at (x cm, y cm) {isibling};

        }

    }

end{tikzpicture}

I get the tree like the following picture. The texts are nodes' isibling within each layer. Most nodes are integers, but all leftmost nodes are not.
