-1,0,3,8,15,24,...
nth term of this sequence is
a%5Bn+%5D=+%28n+-+2%29+n (for all terms given) if n starts from 1
-1, 0, 3, 8, 15, 24, 35, 48, 63, 80, 99, 120, 143, 168, 195, 224, 255, 288, 323, 360, ....

-4,0,6,14,24,36,...
a%5Bn+%5D=+n%5E2+%2B+n+-+6 (for all terms given) n starts from 1
-4, 0, 6, 14, 24, 36, 50, 66, 84, 104, 126, 150, 176, 204, 234, 266, 300, 336, 374, ...
