According to the following rule, form a number table with positive integers, then which row and number is 2008 in the table 1;2,3;4,5,6;7,8,9,10;………………

According to the following rule, form a number table with positive integers, then which row and number is 2008 in the table 1;2,3;4,5,6;7,8,9,10;………………

If n = 62.8 is obtained from the sum of the first n terms of the arithmetic sequence, then 2008 is in line 63. If the last number in line 62 is 62 + 62 * 61 / 2 = 1953, then 2008 is in line 2008-1953 = 55
