Answer:

  • 8, 20, 32, 44, 56
  • arithmetic

Step-by-step explanation:

The words "common difference" tell you this is an arithmetic sequence. A geometric sequence will have a common ratio between terms.

__

The common difference is added to each term to get the next.

  first term: 8 -- given

  second term: first term + common difference = 8 + 12 = 20

  third term: 20 +12 = 32

  fourth term: 32 +12 = 44

  fifth term: 44 +12 = 56

The first 5 terms of this arithmetic sequence are 8, 20, 32, 44, 56.
