For each statement: True or false? Explain?
If the terms sn of a convergent sequence are all positive then lim sn is positive. If the sequence sn of positive terms is unbounded, then the sequence has a term greater than a million. If the sequence sn of positive terms is unbounded, then the sequence has an infinite number of terms greater than a million. If a sequence sn is convergent, then the terms sn tend to zero as n increases....
