Determine whether the sequence is arithmetic. If so, then find the common difference. $$80,40,20,10,5, \dots$$
Added by Sharon W.
Step 1
To determine if a sequence is arithmetic, we need to check if there is a constant difference between consecutive terms. Let's check the difference between the first two terms: $$40-80=-40$$ The difference is not constant, so the sequence is not arithmetic. Show more…
