i +=k;

Answer 1

Hello Rocky Francisco

Please add the programming language to the tags.

I guess this is js.

var i = 1;
for (k=1;k<10;k++)
i+=k;

console.log(i); //output 46

k = 1, i = 1
i += k -> i = i + k -> i = 1 + 1

k = 2, i = 2 //i += k = 4
k = 3, i = 4 //i += k = 7
k = 4, i = 7

....

k = 9, i = 37 //i += k = 46
k = 10 -> end loop.

Answer 2

is it kotlin? may be there is a mistake in your second line

var = 1;
for (k=1;k<10;k++)
i+=k;

run this code now.
