This shows how to find the nth term for a cubic sequence.

4 15 44 103 204
1st diff 11 29 59 101
2nd diff 18 30 42
3rd diff 12 12 so 12/6=2 It is a 2n^3  sequence

Do a 2n^3 line 2 16 54 128 250

Take this away from the original sequence

2 -1 -10 -25 -46

This is  a quadratic sequence
1st diff -3 -9 -15 -21
2nd diff -6 -6 -6 -6 -6/2=-3
-3n^2
Do a -3n^2 line -3 -12 -27 -48

Take this away from the quadratic sequence 5 11 17 23. This is linear, the difference is 6 so it is a 6n-1 sequence and the complete rule is 2n^3-3n^2+6n-1

hi
do u have notes on digital electonics in physics?(like all the logic gates and stuff). I also need notes on how to do find the formula on linear and quadratic sequence in maths.
Thanks
