Determine if the following statement is true or false. If true give a reason or cite a theorem and if false, give a counter example. 

1) (a) Determine if the following statements are true or false. If true give a reason or cite a theorem and if false, give a
counterexample.
i) If {a,} is bounded, then it converges.
ii) If {a, } is not bounded, then it diverges.
iii) If {a,} diverges, then it is not bounded.
(b) Give an example of divergent sequences {a, } and {b,} such that {a, + b,} converges.
