a) 29,30,31,32,33
Notice the number of numbers in each column have this pattern :
1,3,5,3,1,3,5,3
And the numbers get bigger down the column.
Notice the number of numbers in each column have this pattern :

And the numbers get bigger down the column.
b)
Notice that for every 4 columns,the pattern repeats.
Every '1,3,5,3' set has 12 numbers. And they take up 4 columns.
So the first four sets have 48 numbers, and take up the first 16 columns.
Therefore, number 49 must be in column 17

Now, for column 300,
300 ÷ 4 = 75
So there are 75 sets of 4 columns.
This means a total of 75 x 12 = 900 numbers.
Remember the pattern 1,3,5,3.
So the last column is a column with 3 numbers. The last 3 numbers must be 898,899,900
300 ÷ 4 = 75
