1. The problem statement, all variables and given/known data
I'm supposed to answer true or false on whether or not the sequence ((-1)^n * n) tends toward both ±∞
2. Relevant equations
Uniqueness of Limits
3. The attempt at a solution
I did prove it another way, but I would think that uniqueness of limits (as a definition available for use) is enough to disprove this statement.
