Graphs and Arithmetic Sequence

Is this sequence arithmetic, geometric, or neither?
{26, 22, 18, 14, ...}

• Arithmetic

• Geometric

• Neither

Fill in the blanks: Arithmetic sequences are graphed as _________ functions.

• Linear

• Exponential

Is this a graph of an arithmetic or a geometric sequence?

• Arithmetic

• Geometric

What are the first three terms of the sequence defined by the following equation?
a_n = 7 + (n - 1)5

• 7, 35, 175

• 7, 2, -3

• 12, 17, 22

• 7, 12, 17

Write a function to represent the sequence:
 -12, -11.75, -11.5, -11.25…?

• f(n) = 0.25n - 12

• f(n) = -0.25(n - 1) - 12

• f(n) = 0.25n - 12.25

• f(n) = 12(n -1) - 0.25

What is the explicit formula the following arithmetic sequence?

• 3(2)^n-1

• 2(3)^n-1

• 3 + 3n

• 3n

Linear Functions relate to the:

• A. Geometric Sequence

• B. Arithmetic Sequence

• C. Exponential Sequence
