Cauchy sequences of real numbers form a real linear space under termwise addition and multiplication by scalars. Cauchy sequences are bounded sequences, and the real linear space bounded sequences of real numbers has a well-known norm, which yields a norm on the space of Cauchy sequences of real numbers.
