How do I add an increase number to a string?

while true do
Wait (7)
Script.Parent.TextLabel.Text.Name = "Round 1"
Wait (2)
Script.Parent.TextLabel.Text.Name = ""
Wait (14)
End

(Keeps repeating and adding increase number)
E.g. Script.Parent.TextLabel.Text.Name = "Round <What I want to increase>"

Hello scripters, is there a way I can increase the number inside a string while keeping some text the same?

Thank you :)
