a geometric series has 3 terms. the sum of the three terms is 42. the third term is 3.2 times the sum of the other two terms. what are the three terms?
the other 2 terms have to be smaller by a constant multiple knowing the number 32 divides nicely by 8 and 4 we can try both of those number i started with 8 so 8times4 gives you 32 and if you divide 8 by 4 you get 2 8=y and x=2 x+y=10 those work!! hope this helps
