If a sequence
is convergent, then there exist
, where
is a constant.
The sequence is
.

Note that the limit is of the form
.
Apply L
Hospital
s Rule :
So, L
Hospital
s Rule tells us that if we have an indeterminate form
or all we need to do is differentiate the numerator and differentiate the denominator and then take the limit.
.

Thus, the sequence converges to
.
The sequence converges to
