| 1.6 | 16bc | Clearly state whether or not the argument is correct and give the specific rule(s) of inference or fallacy used.
| | 20 | Explain why or why not, specifying rules of inference/fallacies.
| | 1.7 | 2 | Be very precise, using the definition of even. You cannot not say, for instance, that 10x+14y-6z+12 is even. You must use algebra to make it look like 2k for some integer k. Similarly for future problems dealing with with either odd or even numbers. Also, a common mistake on this kind of proof is to write it in such a way that you are essentially assuming the two numbers are the same number without realizing it.
| | 18 | Take the assumption that n is an integer as a given, and read the problem as "If 3n+2 is even, then n is even."
