Click and drag the steps in the correct order to show that 6 divides n³. - n whenever n is a nonnegative integer using mathematical induction. BASIS STEP: INDUCTIVE STEP: 61 (131), i.e., 610, the basis step is true. 61 (03-0), i.e., 610, so the basis step is true. Suppose that 61 k³ - k. By the inductive hypothesis, 6 I (K³-k). Clearly, 31 3k(k+ 1), but 3k(k+ 1) is also even as one of k or k+ 1 is even; therefore, 6 1 3k(k+ 1) as well. By the inductive hypothesis, 3 I (k³ - k). Clearly, 31 3k(k+ 1), but 3k(k+ 1) is also odd as one of kor k + 1 is even; therefore, 6 | 3k(k+ 1) as well. (k+ 1)³(k+ 1) = (k³ + 3k² + 3k + 1) - (k+ 1) = (ksk) + 3k(k+1) As the sum of two multiples of 6 is again divisible by 6, 61 ((k+ 1)³-(k+ 1)).
