What is the slope of a line passing through the points (2, 4) and (4, 6)?
1
Solve for x:
x + 2 = 10
x = 8
Is this sequence Arithmetic, Geometric, or Neither?
2, 6, 18, 54, 162
Geometric
What is the first term of this Explicit Sequence?
An = 2n + 3
5
Solve for x:
3x - 2 = 10
x = 4
Is this sequence Arithmetic, Geometric, or Neither?
1, 5, 6, 9, 10
Neither
What are the first four terms of this Explicit Sequence? An = 4n + 1
5, 9, 13, 17
Is Slope "rise over run," or "run over rise?"
rise / run
Solve for x:
2x + 3 = x - 6
x = -9
Is this sequence Arithmetic, Geometric, or Neither?
3, 5, 7, 9, 11
Arithmetic
What is the difference between the Explicit Formula and the Recursive formula?
Explicit: substitute in the number of each term (1 for 1, 2 for 2, etc)
Recursive: substitute in the term before
Solve for x:
3x + 6 = x + 10
x = 2
What is the second term of this Recursive Sequence? A1 = 2
An = an-1 + 2
4
Solve for x:
x2 - 5 = 20
x = 5
What are the first four terms of this Recursive Sequence?
A1= 0
An = an-1 - 4
0, -4, -8, -12
