The question asks:

For each element, predict where the "jump" occurs for successive ionization energies.  For example, does the jump occur between the first and second ionization energies, the second and third, or the third and fourth?

The book gives a few examples of elements and provides the answers, but I do not understand how it gets the answers.  For Be, it says the jump occurs between the 2nd and 3rd.  For O it says between the 6th and 7th.  For N it says between the 5th and 6th, and so on.

What do I have to do or know in order come to these conclusions?

Thanks in advance.

The jump occurs when you start emptying a once full orbital. For example, in Oxygen the jump occurs between 6 and 7 because once you remove the 7th electron it has gone up one row on the periodic table. This means you emptied the n = 2 level and are now removing from the n = 1 level which was full to begin with. That is very energetically unfavorable to do.
