0 "+3" 3 "+5" 8 "+7" 15 "+9" 24 "+11" 35 "+13" 48 "+15" 63

Starts with 3 then adds another 2 each step

The next number is 35. The nth term rule = n2-1 (ie n squared minus one).

Does that make any sense to you? You can work this out by drawing a table with n across the top and the sequence below, then in the next row working out the difference between each number in the sequence (the differences are 3, 5, 7, 9 etc). Then draw another row in the table showing the differences between the differences - they are all 2. This tells you that the nth term is a quadratic, ie it involves n squared. Once you know this, it is evident that the full term must be n2-1.

I hope that makes sense. I recommend that you ask your maths teacher about this though, because you need to make sure you really understand it.

Feel free to ask for more explanation if all this has been gobbledegook.
