2 Proof:
3 Proof: We suppose...
4 that 3n + 7 is even.
5 that 3n + 7 is even. Since n is odd, there exists an integer k so that n = 2k + 1.
6 that 3n + 7 is even. Since n is odd, there exists an integer k so that n = 2k + 1. By substituting for n and using algebra, we get 3n + 7 = 3(2k + 1) + 7
7 that 3n + 7 is even. Since n is odd, there exists an integer k so that n = 2k + 1. By substituting for n and using algebra, we get 3n + 7 = 3(2k + 1) + 7 3n + 7 = 6k
8 that 3n + 7 is even. Since n is odd, there exists an integer k so that n = 2k + 1. By substituting for n and using algebra, we get 3n + 7 = 3(2k + 1) + 7 3n + 7 = 6k n + 7 = 6k + 10
9 that 3n + 7 is even. Since n is odd, there exists an integer k so that n = 2k + 1. By substituting for n and using algebra, we get 3n + 7 = 3(2k + 1) + 7 3n + 7 = 6k n + 7 = 6k n + 7 = 2(3k + 5).
10 that 3n + 7 is even. Since n is odd, there exists an integer k so that n = 2k + 1. By substituting for n and using algebra, we get 3n + 7 = 3(2k + 1) + 7 3n + 7 = 6k n + 7 = 6k n + 7 = 2(3k + 5). Since k is an integer, 3k + 5 is also an integer because integers are closed under addition and multiplication.
11 that 3n + 7 is even. Since n is odd, there exists an integer k so that n = 2k + 1. By substituting for n and using algebra, we get 3n + 7 = 3(2k + 1) + 7 3n + 7 = 6k n + 7 = 6k n + 7 = 2(3k + 5). Since k is an integer, 3k + 5 is also an integer because integers are closed under addition and multiplication. If we let q be the integer 3k + 5, then by substitution we have shown 3n + 7 = 2q.
12 that 3n + 7 is even. Since n is odd, there exists an integer k so that n = 2k + 1. By substituting for n and using algebra, we get 3n + 7 = 3(2k + 1) + 7 3n + 7 = 6k n + 7 = 6k n + 7 = 2(3k + 5). Since k is an integer, 3k + 5 is also an integer because integers are closed under addition and multiplication. If we let q be the integer 3k + 5, then by substitution we have shown 3n + 7 = 2q. Therefore, if n is an odd integer, we have shown that 3n + 7 is even.
13 that 3n + 7 is even. Since n is odd, there exists an integer k so that n = 2k + 1. By substituting for n and using algebra, we get 3n + 7 = 3(2k + 1) + 7 3n + 7 = 6k n + 7 = 6k n + 7 = 2(3k + 5). Since k is an integer, 3k + 5 is also an integer because integers are closed under addition and multiplication. If we let q be the integer 3k + 5, then by substitution we have shown 3n + 7 = 2q. Therefore, if n is an odd integer, we have shown that 3n + 7 is even.
14 Alternative proof: that 3n + 7 is even. Since n is odd, there exists an integer k so that n = 2k + 1. By substituting for n and using algebra, we get 3n + 7 = 3(2k + 1) + 7 = 6k = 6k + 10 = 2(3k + 5) = 2q, where q = 3k +5 is an integer because k is an integer, and integers are closed under addition and multiplication. Therefore, we have shown that 3n + 7 is even when n is an odd integer. QED

16 Writing Guidelines We do not consider a proof complete until there is a well-written proof. 0. Do all of the thinking, work, and planning first. A Know-Show table or outline or notes or scratch work should be completed prior to writing so you can focus on quality writing, not math.

Tell the reader when you are done. Give some form of QED: Quod Erat Demonstrandum - which was to be demonstrated. Use whatever symbol you like: or or or or $.
