The Fibonacci series is one in which the addition of two previous terms gives you the next term. That is. 0,1,2,3,5,8,13....1 + 2 is the next consecutive term which is 3, so is 3 + 5 (the next term.

This program uses a function subprogram to call by value.

Program Fibnacci;
Var
I : integer;
Function fibonacci (a: integer): integer;
Begin
If a=1 then
   Fibonacci :=0
Else if n=2 then
    Fibonacci :=1
Else
    Fibonacci := Fibonacci(a-1) + Fibonacci (n-2);
End;
Begin
For I:= 1 to 20 do
Writeln(Fibonacci (I));
Readln
End.

Who is this for exactly?

Whoever actually needs it

Go to d thread "I want to Learn programming ... " and rewrite ur program in one of d languages suggested there in d responses.
Then,ur program wud b more useful.
