%N A117619 a(n) = n^2 + 7 with a(0) = 7.

Well, we already have:

A002522    n^2 + 1.
A059100    n^2 + 2.
A087475    n^2 + 4.

We could admit members of the family n^2 + k up to some value of k such as
k=9, but it would be nice to see some mathematical justification beyond
completing the set.

I wonder why no-one has submitted n^2 + 3?

Dear all,
After so long and hot discussion
about OEIS, 
we have new sequences as this one:

%N A117619 a(n) = n^2 + 7 with a(0) = 7.

Could anyone please explain what is the meaning of it?
