Question

In Fibonacci series, the next number is the sum of previous two numbers. The series starts with 0 and 1, and then the next numbers are a sum of the previous 2 numbers.
For example 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55 etc.
Here the first 2 numbers are 0 and 1
The next numbers are:
1 (= 1 + 0)
2 (= 1 + 1)
3 (= 2 + 1)
5 (= 3 + 2)
And so on…
Write a program the first n numbers of the Fibonacci series.
Hint: You already know the first 2 values. How can you calculate the remaining?

Answer 1

Answer:

it is the correct answer

Answer 2

Answer:

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")

# if there is only one term, return n1

elif nterms == 1:

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

print(n1)

# generate fibonacci sequence

else:

print("Fibonacci sequence:")

while count < nterms:

print(n1)

nth = n1 + n2

# update values

n1 = n2

n2 = nth

count += 1
