Just write your loop to display the loop counter on each cycle of the loop:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

Once you have that working, put an "if" statement inside the loop to display a \n after the loop counter if the counter is 1 or 3 or 6 or 10 or 15.

for(i=1;i<n;i++) {
for(j=0; j<i, j++) {
print(i+j);
}
}

You don't need nested loops. Just one loop will do:

 
for(i=1;i<=15;i++) {
print(i);
print(space);
}

This will print 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15.

Now just insert an "if" statement between the two prints to print a newline (\n) if the counter i is 1 or 3 or 6 or 10 or 15.
