Find the sum of the infinite geometric sequence (if it exists). (A) 3, - 9, 27, - 81, 243, ... 1 1 1 (B) 2, 1, 2 4 8If a person borrows $3,000 and repays the loan by paying $100 per month to reduce the loan and 1% of the unpaid balance each month for the use of the money, what is the total cost of the loan over 30 months? E) The total cost of the loan is $|:|. (Type a whole number.) Let a1, 32, 33,..., an.... be an arithmetic sequence. Find a6 and S16. 31:11,d=6 a6=|:| (Simplify your answer.) The government, through a subsidy program, distributes $10,000,000. If each person or agency spends 30% of what is received, and 30% of this is spent, and so on, how much total increase in spending results from this goverment action? (Let a1 = 3,000,000.) <:> The total increase in spending will be approximately $D. (Round to the nearest dollar as needed.) Find any of the values a, , r, a, n, or S, that are missing from the geometric sequence. 4 r= 7, n= 4, S4 = 175 . . . The value of a, is (Simplify your answer. Type an integer or a fraction.)
