The third sequence.
Step-by-step explanation:
In an arithmetic sequence, the difference between two consecutive terms is the same.
For each option, find the difference between consecutive terms:
First option:
The differences are not the same. As a result, this option is not an arithmetic sequence.
Second option:
The differences are not the same. As a result, this option is not an arithmetic sequence, either.
Third option:
The differences are all
. As a result, this option is indeed an arithmetic sequence. Its common difference is
.
Fourth option:
The differences are varying between
and
. As a result, this option is not an arithmetic sequence.
