Determine whether the sequence 8, 4, -2, -6, … is arithmetic, geometric, or neither.
Added by Pedro W.
Step 1
For an arithmetic sequence, there is a common difference between each term. To check if this sequence is arithmetic, we can subtract each term from the previous term: 4 - 8 = -4 -2 - 4 = -6 -6 - (-2) = -4 We can see that there is a common difference of -4 Show more…
