Write the Terms of a Sequence Defined b a Recursive Formula 76) First we show that the statement is true when n =. For n =, we get = (6-3 - ) =. This is a true statement and Condition I is satisfied. Net, we assume the statement holds for some k. That is, (3k - ) = k(6k - 3k - ) is true for some positive integer k. We need to show that the statement holds for k +. That is, we need to show that (3(k + ) - ) = (k + )(6(k + ) - 3(k + ) - ). So we assume that (3k - ) = k(6k - 3k - ) sides of the equation (3k - ) + (3(k + ) - ) = k(6k - 3k - ) is true and add the net term, (3(k + ) - ), to both + (3(k + ) - ) = k(6k - 3k - ) = k(6k - 3k - ) + (3k + ) + (9k + 6k + )

22 Answer Ke Testname: SPRINGFINALREVIEW = 6k3-3k - k + 8k + k + = 6k3 + 5k + k + Simplif the epression (k + )(6(k + ) - 3(k + ) - ) to verif: (k + )(6(k + ) - 3(k + ) - ) = (k + )(6(k + k + ) - 3k -3 - ) = (k + )(6k + k + 6-3k - ) = (k + )(6k + 9k + ) = 6k3 + 5k + k + Condition II is satisfied.
