Write a program that will add up the sum of a series of numbers starting at 1 up to the number entered as in 1 + 2 + 3 + 4 + 5 = 15, where 5 was the number entered.

Answer 1

n = int(input("Enter a positive integer for n: "))

total = 0
i = 1
while i <= n:
    total += i
    i += 1

print("Sum of integers from 1 to {} is {}".format(n, total))

display "Enter a positive integer for n: "
read n

set total to 0

for i from 1 to n
    add i to total
end for

print total

Input: 5, Output: 15
Input: 6, Output: 21
Input: 10, Output: 55
Input: 100, Output: 5050
