... 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...
