A002675 / 1, 1, 1, 17, 31, 1, 5461, / what is this?

[Gottfried Helms]

Hi,

 dealing with some bernoulli-analog numbers I came across that
 sequence of numbers, but I don't know how how to relate
 the given sparse explanation to my results. What is meant here
 with "central differences" (don't have access to the
 reference)?
