  The metallic means (also known as metallic ratios) may be defined as the
limiting ratio of consecutive terms of sequences connected to the Fibonacci
sequence via the INVERT transform. For example, the Pell sequence (invert
transform of the Fibonacci sequence) gives the so-called silver mean, and the
invert transform of the Pell sequence leads to the bronze mean. The limiting
ratio of the Fibonacci sequence itself is known as the golden mean or ratio. We
introduce a new family of kth-degree metallic means obtained through invert
transforms of the generalized kth-order Fibonacci sequence. As it is the case
for k=2, each generalized metallic mean is shown to be the unique positive root
of a kth-degree polynomial determined by the sequence.
