Extract value if sequence is respected in a table

Hi,

I have a table of 2 columns: Orders and Operations.
An order normally starts with an operation 0010 and if needed, an operation 2 is added with the code 0020 and so on.
IE1: If an order needs 5 operations, we would have: Operation 0010, 0020, 0030, 0040 and 0050.

However, it is possible for someone to delete one of the operation.
IE2: If we take IE and someone deletes the 0010 and 0020, the order would only have the operation 0030, 0040 and 0050.

Is it possible to extract all orders that have deleted operation and all the deleted operations?
