How do you make a transparency brick, that follows a pattern? (0.1 0.2 0.3 0.4 0.5)

I need to learn how to do this.

while true do 
script.Parent.Transparency = 0 
wait(3)
script.Parent.Transparency = 0.1
wait(3) 
script.Parent.Transparency = 0.2
wait(3)
script.Parent.Transparency = 0.3
wait(3)
script.Parent.Transparency = 0.4
wait(3)
game.Parent.Transparency = 0.4
end  -- DONT TOUCH THIS`

--Change the "(3)" to the time you want.
