Arithmetic and Geometric Sequences

What is the distance from one number to the next in a sequence of numbers that is represented by a (d) in an arithmetic sequence?

• Common denominator
• Common opposites
• Common domain
• Common difference

Each individual number in a sequence of numbers is called what?

• Common difference
• Successive term
• Term
• Geometric term

Which kind of sequence has a common difference?

• Arithmetic
• Geometric

A _____________sequence is a sequence of numbers in which the ratio between any two consecutive terms is a constant. 

• Geometric Sequence
• Arithmentic Sequence

225,75,25,8.33

• Geometric sequence with a common ratio of 1/3
• Geometric sequence with a common ration of 3
• Arithmetic sequence with a common difference of 58
• Common difference of 3

Find the 22nd term of the following sequence:
5, 8, 11, ...

• 14
• 68
• 63
• 71

Create the explicit formula for the sequence:
2, 8, 14, ...
(Hint:  Write your formula and then simplify it.)

• a_n=2+6n
• a_n=-6+6n
• a_n=6n-4
• a_n=4-6n

Identify the common difference.
97, 86, 75, 64, ...

• 8
• 11
• -11
• -8

Write the explicit formula for the geometric sequence.

• a_n = 10(2)^n-1
• a_n = 2(10)^n-1
• a_n = 10(2)ⁿ
• a_n = 2(10)ⁿ
