Sequences

Sequence equations rely on previous values to derive new ones. They use formulas that help find the ext one, instead of guessing. Arithmetic sequence is when your adding together or subtracting, Geometric is multplying or dividing. The Recursive formula, helps you find the next value in the graphing, but when you use the Explicit frmula, you can use it to find any number, without depending on the last one.


Example (Geometric//Recursive):
A(n)=(An-1) x 3

n An
_
1 3
2 9
3 27
4 81
