I am not certain of the repetition.

starts at 18, down 34, then down 3, ...

I would like to have another term or two. Frankly, if it keeps going down, it cannot be 44, as the highest value will be 18 at the start.

Well, since the first three terms shown add to 47, you got me.

Now, if we continue, with the difference increasing by one each term, we get

18 16 13 10 5 -1 ...
If we add terms 2 through 5 we get 44.

An odd problem, and, I suspect, garbled in transit.
