... year is 55.89*(1.03)^19 = 98.0034533 (c) The formula of a geometric series is a(r^n-1)/(r-1). Thus, the total of all the payments...
Let a be the first term, r be the common ratio, so a(ar)(ar^2)=343 ==> (ar)^3 = 343 ==> ar = 7 ⋯⋯⋯⋯ (i) a+ar+ar^2 = 24.5 ==> a(1+r+r^2) = 24.5 ==> (7/r)(1+r+r^2) = 24.5 ⋯⋯ (from (i)) ==> 1+r+r^2 = 3.5r ==> r^2-2.5r+1=0 ==> (r-0.5)(r-2)=0 ==> r=0.5 or 2 When r=0.5, from (i), a...
