Let{xn} be a sequence of real numbers that is bounded above by M and such that
xn ® x . Prove that x £ M .
we know that
Asequence {xn} is bounded if there exists an x ÎX and a real number
M > 0 such that d (xn , x) £ M for all n . also it convergent to x.
how can I use this to prove. any help will be apprciated.
