∫20 1 1 is not a multiple of 2.

∴20 1 1 is odd; ∴ 1~20 1 1 The number of positive numbers and odd numbers is1005+1=1006.

∫ There are 8 numbers in each line: 20 1 1 which line:1006 ÷ 8 =125 ミ Line ミ. ...................................................................................

∴20 1 1 in the sixth column of line 126.

(2) The number at the top left of the box number is n; Then the other three numbers are | n+2 |, | n+ 16 | and | n+ 18 | respectively.

∴n+n+2+n+ 16+n+ 18= 14 16

4n+36= 14 16

4n= 1380

n=345

∫ ~ 345-1~ 2+1=173 ~ pieces.

173 ÷ 8 = 2 1 (line) ...........................................................................................................................................

∴345 in line 22, column 5

Can be framed in the diagram.

These four numbers are: 345, 347, 36 1, 363.
