Question

write a program to print the fibonacci sequence 1,2,3,5,8,13,21,34,..​

Answer 1

Answer:

# Program to display the Fibonacci sequence up to n-th term

nterms = int(input("How many terms? "))

# first two terms

n1, n2 = 0, 1

count = 0

# check if the number of terms is valid

if nterms <= 0:

print("Please enter a positive integer")

elif nterms == 1:

print("Fibonacci sequence upto",nterms,":")

print(n1)

else:

print("Fibonacci sequence:")

while count < nterms:

print(n1)

nth = n1 + n2

# update values

n1 = n2

n2 = nth

count += 1

Answer 2

C program to print the Fibonacci sequence of 1,2,3,5,8,13,21,34

#include <stdio.h>

int main()

{

 int first = 1, second = 2, third, n, i;

 printf(" Enter the number of terms: ");

 scanf("%d", &n);

 printf("%d %d", first, second);

 for (i = 3; i <= n; i++)

 {

  third = first + second;

   printf(" %d", third);

   first = second;

   second = third;

 }

 return 0;

}

OUTPUT

Enter the number of terms: 8

1  2  3  5  8  13  21  34
