Answer:
- 8, 20, 32, 44, 56
- arithmetic
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.
