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