If instead, the investment outflow of ₀ = 1 per customer yielded a perpetual revenue stream such that each payment grows at a constant geometric rate over time so that the perpetual cash flow stream looks like = (₁, ₂, ₃, ₄, ... ) = (2, 3, 4.5, 6.75, ... ), compute the net present value (per customer) of investing in this technique at a discount rate of 100%.
