Today in class we learned about sequences.
1) Arithmetic Sequence- the sequence where the next term is found by adding/subtracting
2)Geometric Sequence- the sequence where the next term is found by multiplying/dividing

Recursive- the next term is based on the previous term.
t9=t8 x 2

Explicit- the term is defined by it's position(term number)

t9=9 x _?_

t1 t2 t3................ t10
2 4 8 t10=2^10

The Fibonacci Sequence is: 1,1,2,3,5,8,13,. . . .

We also learned how to find sequences on our calculator:

Ex) Week Prize
1 t1 5
2 t2 10
3 t3 20

1)mode--->seq
2)y=
nMin= what the first term is called----->1
u(n)=recursive formula (*always* u(n-1))---------> u(n-1) x 2
u(nMin)=first term (where you start)-------> {5}

So, to find week 52 go to 2nd function window and change the tblstart=52
