Definition :-

In mathematics,theFibonacci Number are numbers in following integer sequence 3,5,8,13,21,34,55

Fn=Fn-1 +Fn-2

where seed Values F1=1 and F2=1

The first 11 Fibonacci numbers Fn for n=0,1,2,....,11 are

f0	f1	f2	f3	f4	f5	f6	f7	f8	f9	f10	f11
0	1	1	2	3	5	8	13	21	34	55	89

PYTHON CODES

When the series start with any two consecutive user define no's

num1=input( 'Enter first no ') num2=input( 'Enter second no ') Tno=input('NO of terms in Series') print num1 print num2 while(Tno-2): c=num1+num2 num1=num2 num2=c print c Tno=Tno-1

---

When the series start with 1 and user define Terms

num1=1 num2=1 Tno=input('NO of terms in Series') print num1 print num2 while(Tno-2): c=num1+num2 num1=num2 num2=c print c Tno=Tno-1
