223. Cash flows that grow at a rate g every odd year have the following structure C1Ci+1Ci+1=C=Cii{1,3,5,7,9,}=Ci(1+g)i{2,4,6,8,10,} This implies that the cash flow in year 1 and 2 is C, in year 3 and 4 is C(1+g), in year 5 and 6 is C(1+g)2, etc. Derive the closed-form/analytical expression for this infinite discounted sum of cash flows i=1(1+r)iCi Assume r>g>0
