Can someone PLEASE give me the answer to the nth term of these:
1) 9, 12, 17, 24, 33, 44
2) -4, -1, 4, 11, 20, 31
3) -3, 3, 13, 27, 45, 67
4) 0, 3, 8, 15, 24, 35
Hated quadratic sequences when it came to the nth term - you're doing A*/A work there I think, and it's stuff I never really properly understood either.
See if this helps you:

The answer to Q1 should be n2 + 8.
