(100 + 1) * 50
Gauss was great!

Why don't you try it yourself, and post the code if you have trouble? We'll be here to help. 😉

try this, hope it helps
i = 1
sum = 0
while i ≤ 100:
sum += i
print(sum)

i'll try, thanx @blackcat1111

1+100=101
2+99=101
and so on untill 50+51=101
so...
50*101

use the sum of arithmetic progression :
Sn = n*(2*a+(n-1)*d)/2
For your question
n = 100
a = 1
d = 1
Therefore :
Sn = 100*(2+99)/2
= 50*101
= 5050
Thus the sum is : 5050
