%N A117619 a(n) = n^2 + 7.
%F A117619 a(n)=2*n+a(n-1)-3 (with a(1)=7) [From Vincenzo Librandi (vincenzo.librandi(AT)tin.it), 
               Nov 07 2009]
%e A117619 If n=1 then n^2 + 7 = 1^2 + 7 = 8 which is the second term.
%e A117619 For n=2, a(2)=2*2+7-3=8; n=3, a(3)=2*3+8-3=11; n=4, a(4)=2*4+11-3=16
