This calculator computes the Fibonacci sequence, the Pell sequence, the Padovan sequence, and the Perrin sequence, and calculates the ratios of their adjacent terms.
As n approaches infinity, the ratios become the golden ratio, the silver ratio, and the other two become plastic numbers.
Fibonacci sequence: P(n) = P(n-1) + P(n-2), P(0) = 0, P(1) = 1
Per sequence: P(n) = 2*P(n-1) + P(n-2), P(0) = 1, P(1) = 2
Padovan sequence: P(n) = P(n-2) + P(n-3), P(0) = 1, P(1) = 1, P(2) = 1
Perrin sequence: P(n) = P(n-2) + P(n-3), P(0) = 3, P(1) = 0, P(2) = 2
