You need to create a background sprite, then make an identical one positioned at the end of the first sprite, then you tween the two sprites together at the same time. When the sprites finish moving, you reset the positions of the sprites and tween them again so that it loops.

You can use this script :

local width = 0
local spriteName = "limoSunset" -- replace limoSunset with the name of your sprite

function onCreate()
    makeLuaSprite("bg1", spriteName, 0, 0)
    width = getProperty("bg1.width")

    makeLuaSprite("bg2", spriteName, width-20, 0)

    addLuaSprite("bg1", false)
    addLuaSprite("bg2", false)

    doTweenX("bg1Tween", "bg1", -width, 5, "linear")
    doTweenX("bg2Tween", "bg2", -20, 5, "linear")
end

function onTweenCompleted(tag)
    if tag == "bg1Tween" then
        setProperty("bg1.x", 0)
        setProperty("bg2.x", width-20)

        doTweenX("bg1Tween", "bg1", -width, 5, "linear")
        doTweenX("bg2Tween", "bg2", -20, 5, "linear")
    end
end
