Sum of Infinite Geometric Sequence

geometric series
The sum of the finite initial segments of the series is:
$\dfrac {a \paren {r^n - 1} } {r - 1}$,
whence, if the infinite series converges, its sum is $a / \paren {r - 1}$.

Lucas Numbers

Lucas numbers
the sequence of integers
$2, 1, 3, 4, 7, 11, 18, 29, \dotsc$
derived from the same difference equation as the fibonacci numbers, but using different initial values. (Named after the English mathematician Henry Lucas (died 1663).)
