Given the sequence:

16, 21, 26, 31

Determine if the given sequence is geometric, arithmetic or neither.

Explanation:

To determine what kind of sequence we have, we simply look at the sequence , and observe to what extent is it decreasing or increasing. In our case, it can be seen that the given sequence is increasing in a constant value. We can conclude this assumption by finding the common difference.

Solution:

Common Differece = 2nd term - 1st term

Common Difference = 21 - 6

Common Difference = 5

Final answer:

Common Difference = 5
