geez, it's a math question -- why all those words?
f(x) = (x+1)/x
f(x) = 1 + 1/x
the sequence is clearly monotonic and convergent (limit = 1)
Hmmm. Maybe you meant
f(x) = x + 1/x
That is clearly unbounded, since x→∞
Next time make it clear what you mean. Words do not do well expressing math, unless you are very careful.
Bottom line:
It's not my job to figure out what you mean. It's your job to say it so clearly you cannot be misunderstood.
