It's a question for the moon

        int total=0;
        for(int i=1; i<100; i++){
            total=total+i;

            System.out.println(total);
            }
        }

It's this chord. From what I've tried, 1 3 6 10 15 21 28 36 45 55 It stretches out like this It comes out up to 4950

But I don't know how it stretches like this

total:0 i:1 added value: 1
Total:1 i:2 added value:3
Total:2 i:3 added value:5

Doesn't it stretch like this? It's over five and six, but I don't understand!
