1. The problem statement, all variables and given/known data Let nεZ,Prove that 1-n^2>0, then 3n-2 is an even integer. 2. Relevant equations 3. The attempt at a solution I proved it like this. I think its right but im not able to word it correctly. Since 1-n^2>0 therefore n=0. Then 3n-6=3(0)-6=-6. Since 0 is an integer, 3n-6 is even. How can I learn to word this correctly because im having some trouble with it?
