- 1What is an arithmatic sequence?The diffrents between the terms are the same.
Arithmatic---> 2,3,6,8
D=+2 - 2What is a geometric sequnce?a geometric sequence has a constant ratio
2,4,8,16
r=2 - 3what is the explicit rule of an arithmatic sequnce?An=A1+D(n-1)
A=term
N=number of terms - 4What is the geometric explicit rule?An=A1(r)^n-1
R=ratio - 5N=?numeber of terms
- 6R=?ratio
[multiplying or dividing] - 7d=?the difference
[adding or subtracting] - 8ratio is found bydividing a2 by a1
- 9diffrence is found bysubtracting a2 from a1
- 10diffrence is used with?arithmatic
- 11ratio is used withgeometric
- 12ratio is found bydividing a1 by a2
- 13what is a recursive rulegives the beginning terms of a sequnence
- 14geometric recursive rulea subscript n-1 must be in ()
only for geometric - 15remember tostop and think
