Sum of consecutive numbers

Question

I have to calculate the sum of consecutive numbers from 1 to N
This is my attempt at the code:

N= int(input())
for x in range (1 , N):
print (x+N)

for example if the input is 380 my outputs are:
381
382
383
.... etc

anyone can help with the flaw of my code?

Answer 1

N = int(input())
#your code goes here
sum = 0
numbers = range(1,N + 1)
for x in numbers:
sum += x

print(sum)
Try this code

Answer 2

print(sum(range(0, N+1)))

Answer 3

For example:
for x in range (1, 100):
print (x+100)

This code will just add the N number to the iterator (x).

You can do something like:

y=0
for x in range (1, 100):
y+=x
print (y)

Explanation: this will keep adding the numbers to 'y' until N is reached. Then it'll print the final one.

Answer 4

Try this 👇👇👇
N = int(input())
print(N*(N+1)//2)

Answer 5

Or you can try using the sum() function.

N = int(input())

N+=1
num = list(range(N))
total = sum(num)
print(total)

Answer 6

N = int(input())
count = N
x = range(1, N +1)
for i in x:
N = i + N
print(N - count)

Answer 7

This code works

x = 358 * (358+1) / 2
print(int(x))

But as soon as I answer the 2nd test, it counts the first one as incorrect so I’m not able to move onto the third. Is this happening for anyone else? Am I doing something wrong?
