)
In this case, the term 
falls between zero and one.
Consider the infinite geometric series summation:
Since the infinite series summation approaches a finite constant C
and since each term in the series is positive,
the finite series summation in Equation 
is bounded from above by C:
Substituting this result into Equation
and making use of the fact that 
,
and therefore 
, gives
