Answer 3

Here's a O(1)
N = int(input())
print((N/2)*(N+1))

Answer 4

You aren't adding the numbers together in the loop and then output the total after the loop, but just outputting each number in the range.
Note: you shouldn't use 'sum' as a variable name, as it will overwrite the built-in sum() functions name.

Answer 5

Take a number N as input and output the sum of all numbers from 1 to N (including N).
Sample Input
100
Sample Output
5050

Answer 6

print(sum(range(int(input()) + 1)))
