Arithmetic Sequences and Series and Geometric Sequences

Find the 22nd term of the following arithmetic sequence:

5, 8, 11, ...

• 14

• 68

• 63

• 71

Identify the common factor.

96, 48, 24...

• 2

• -48

• 1/2

• -2

Given the sequence:

25, 21, 17, 13,...

Write the explicit equation that models the sequence. HINT: It is an arithmetic Sequence

• a_n = 4n + 29

• a_n = - 4n + 25

• a_n = - 4n + 29

• a_n = 4n + 25

The next two terms of the sequence 4,7,10,13 are ....

• 16 and 19
• 15 and 19
• 16 and 18
• 15 and 18

What kind of sequence is this: 17, 9, 1, -7, ...

• Arithmetic

• Geometric

• Other

7, 11, 15, 19...Write the explicit equation that models the sequence. HINT: It is an arithmetic Sequence

• t(n)= 4n+7

• t(n) = 4n+3

• t(n) = 7n +4

• t(n) = 3n +4

2, 6, 18, 54, ...Write the recursive equation that models the sequence. HINT: It is a geometric sequence

• t(n) = 2 * 3^n

• t(1) = 2

  
  t(n) = 3n

• t(1) = 2

  
  t(n) = 3t(n-1)

• t(n) = 3n
