I do not see any reason for any of the sequences to be listed in the OEIS.
And the author gives us no reason and no explanation, information or 
inspiration.

The sequence seems arbitrary and it is very simple, the given
recursive formula is too complicated.

"a(n)=9*n-a(n-1)-6 (with a(1)=6)" is the same as

"a(n)=9*floor((n+1)/2)-3" which is easier to understand and to evaluate.

I can not imagine who would do a search on
6, 6, 15, 15, 24, 24, 33, 33, 42, 42, 51, 51, 60, 60, ...

At least the keywords should be a combination of dumb,less,easy

There are more new sequences like these, e.g.:
A168411|A168413|A168416|A168418|A168419|A168420
