The positive odd numbers 1,3,5,7 Arrange in five columns according to the format shown in the figure. What is the row and column of 2007?
The positive odd numbers are arranged in 5 columns as follows:
First column second column third column fourth column fifth column
First line 1 3 5 7
The second line 15 13 11 9
The third line 17 19 21 23
The fourth line 31 29 27 25

According to the arithmetic formula: 1 + 2 (n-1) = 2007, n = 1004, so 2007 is the number 1004
1004 / 4 = 251. There is no remainder, so 2007 is the last bit on line 251

The positive odd numbers 1,3,5,7 Arrange in five columns according to the format shown in the figure. What is the row and column of 1997?
One column, two columns, three columns, four columns and five columns
One line 1 3 5 7
Second line 15 13 11 9
Sanxing 17 19 21 23
Four lines 31 29 27 25
Five elements 33 35 37 39

1, 3, 5, 7. This way, 1997 ranked 999,
999 divided by 4 = 249, so 1997 is the third row below 249, which is 250,
And the third is in the third column
PS: because of the special position, the third digit must be in the third column. If it is the first, second and fourth digits, the odd and even rows should be considered

Put the odd number 1, 3, 5, 7. Into five columns in turn (as shown in the figure). Which column does 2007 appear in?
1 3 5 7
15 13 11 9
17 19 21 23
31 29 27 25
33 35 37 39
