Hello - there are several possible causes of low compression on 1 cylinder only. Causes include: burned valve, worn piston rings (not common for a single cylinder), worn camshaft lobes (not allowing full air charging of the cylinder), valve adjustment too tight (leads rapidly to burned valve). I would recommend an engine inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
