1. The problem statement, all variables and given/known data show that the sequence is divergent: xn: 1,0,1,0,1,0,..... 3. The attempt at a solution there exists a number p>0 such that there is no N with the property abs(xn-C)<p where n>N for all n and C is the limit. I don know how to find this value of p. My teacher said that p must be greater than 1/2 but i cant understand why. can someone please explain using very basic explanation. thank you very much.
