If the US government set up a sinking fund to pay off its national debt of approx. $19 trillion dollars, and planned the first payment of $100 billion at the end of the first year. The second and all subsequent payments would increase by 10% per year. At the same time, the national debt would increase by 5% per year. How long would it take the US government to pay off its current national debt of about $19 trillion? Thanks for any help.
