There are many ways to do this. But here is a quick attempt to get you started

T2 = {{1, 0.0112401}, {2, 0.022343}, {3, 0.0263601}, {4,
0.0362769}, {5, 0.0487026}, {6, 0.0443083}, {7, 0.0568229}, {8,
0.0678723}};
Animate[Grid[
{
{Row[{"point ", i, " = ", T2[[i]]}]},
{Graphics[{PointSize[.04], Point[ T2[[i]]]}, Frame -> True,
PlotRange -> {{0, 8}, {-3, 3}}]}}, Spacings -> {1, 1}
] , {i, 1, Length@T2, 1}]


• Thank you may I ask if there a way to show the x-y data together with the moving dot? – Boajj04 Oct 25 at 6:19
