Answer 2

Answer:

a + ar = 3 -----> a(1+r) = 3

a + ar = 3 -----> a(1+r) = 3ar + ar^2 = -6 ---> ar(1+r) = -6

a + ar = 3 -----> a(1+r) = 3ar + ar^2 = -6 ---> ar(1+r) = -6divide the 2nd equation by the first

a + ar = 3 -----> a(1+r) = 3ar + ar^2 = -6 ---> ar(1+r) = -6divide the 2nd equation by the firstr = -2

a + ar = 3 -----> a(1+r) = 3ar + ar^2 = -6 ---> ar(1+r) = -6divide the 2nd equation by the firstr = -2now sub that into the first to get a

a + ar = 3 -----> a(1+r) = 3ar + ar^2 = -6 ---> ar(1+r) = -6divide the 2nd equation by the firstr = -2now sub that into the first to get aand you are all set
