1. The problem statement, all variables and given/known data consider the sequence space l[tex]\infty[/tex](R) of bounded real sequences with the sup norm. If (X(n)) is sequence in l[tex]\infty[/tex](R) and X [tex]\in[/tex] l[tex]\infty[/tex](R), what does it mean to say that (X(n)) converges to X let (X(n)) be the sequence (1,1,---,1,0,0,---) with the first n coordinates 1 and the rest 0. And let x be the sequence (1) with every coordinate 1. Prove that the sequence (X(n)) does not converge to x 2. Relevant equations 3. The attempt at a solution not sure where to start with this. any points to where i can look up info or where to start please?
