Theorem 5.1.1. For all n E N, 1+2+3+...+n = 2 m(a+1) (5.1) The following sentences are enumerated. Put them in order as presented in the lesson material to create a proof of Theorem 5.1.1. that uses an induction argument. Enter your answer as a 6 digit integer. (For example, 123456 is in a valid format for an answer, but it is incorrect.) 1. Inductive step: Assume that P(n) is true, that is equation (5.1) holds for some nonnegative integer n. 2. So it follows by induction that P(n) is true for all nonnegative n . 3. We use induction. 4. Base case: P(0) is true, because both sides of equation (5.1) equal zero when = 0. 5. The induction hypothesis P(n) will be equation (5.1). 6. Then adding n +1 to both sides of the equation implies that n(n + 1) 1+2+3+ +n+ (n +1) : + (n + 1) 2 (n + 1)(n + 2) (by simple algebra) which proves P(n + 1). ||
