Leonardo number
The Leonardo Sequence is the series of numbers:
1, 1, 3, 5, 9, 15, 25 ...
Recursive way
function LeonardoNumber( n : integer ):integer;
begin
if n > 1 then result := LeonardoNumber( n - 1 ) + LeonardoNumber( n - 2 ) + 1
else result := 1;
end;
Making use of Fibonacci numbers
function LeonardoNumber2( n : integer ):integer;
begin
result := 2 * FibonacciNumber( n + 1) - 1
end;
