For questions 1 and 2, identify each sequence as arithmetic, geometric,

both, or neither.

  1. 7,9,11,13,...

Aarithmetic
Bgeometric
Cboth
Dneither



  1. 2,1 ,1/2, 1/4

Aarithmetic
Bgeometric
Cboth
Dneither


For questions 3 and 4, write a rule for the sequence.

  1. 1,2,4,8

AStart with 1 and then add 1 repeatedly

BStart with 1 and then add multiples of 2 repeatedly

CStart with 1 and then add multiples of 2 repeatedly

DStart with 1 and then divide by 2 repeatedly



  1. 50, 40, 30, 20,...

AStart with 50 and then add 10 repeatedly

BStart with 50 and then add -10 repeatedly

CStart with 20 and then add 10 repeatedly

DStart with 50 and then add multiples of 10 repeatedly


  1. Find the next three terms in the sequence.

4, 12, 36, 108


A304, 912, 2736
B324, 972, 2916
C354, 1062, 3186
D332, 996, 2988


Please check my answers

  1. A
  2. B
  3. C
  4. A
  5. A

Please help take your time to check them im not in a rush

Verified Answer :

(1) It is an arithmetic sequence since it has a common difference of 2. The answer is letter A.
(2) It is a geometric sequence since it has a common ratio of 1/2. The answer is letter B.
(3) 
C. Start with 1 and then add multiples of 2 repeatedly 
(4) 
B. Start with 50 and then add -10 repeatedly 
(5) 
C. 354, 1062, 3186

actually #5 is b. 324, 972, 2, 916
