Arrange the natural numbers in the following order: 1 & nbsp; 2 & nbsp; 6 & nbsp; 7 & nbsp; 15 & nbsp; 16 & nbsp 3 5 8 14 17 … 4 9 13 … 10 12 … 11 … In this arrangement, the number 3 is in the first column of the second row, and the number 13 is in the third row and the third column?

The maximum number in the nth diagonal line is & nbsp; Sn = 12n (n + 1), the largest number in the 62nd diagonal row is 12 × 62 × 63 = 1953. The largest number in the 63rd diagonal row is 1953 + 63 = 2016. So 1993 is located in the 63rd diagonal row. The median number in the 63rd diagonal row is increasing from bottom to top, and the first number on the left is 1954. Therefore, 1993 is located in the 63rd diagonal row from top to bottom (1993-1954 + 1) = 40, that is, the original array (63-40 + 1) = 24, column 40 In line 24, column 40

He's worried about being submerged. Ha ha
