First number that comes after a list of numbers

Hello, I have a list of numbers 'indexstart'. I would like to find the 1st number that comes after these number from another list 'indend' and append them both in different columns.

For example:

A = [1, 8, 20]     
B = [4, 5, 6, 9, 25, 30]

The output would be:

[1, 4]

[8, 9]

[20, 25]

Thanks in advance.

ans =
     1     4
     8     9
    20    25
