The number of digits in each row is equal to the number of rows.

So there are 20 numbers in the 20th line, and the total number is1+2+3+4+5+6+7+8+9+10+...+20 = 210.

There are 19 numbers in line 19. 1+2+3+4+...+ 19 = 190.

Line 5: 1/ kloc-0/1,-12,1/3,-1/.

........

Line 20:1191,-1/200,-1/2 10.

So the number 10 in line 20 is-1/200.
