Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form.
5, comma, 11, comma, 17, comma, point, point, .
5,11,17,...
The sequence is arithmetic because there is a common difference between each term.
To find the common difference, we can subtract any term from the following term.
11 - 5 = 6
17 - 11 = 6
Therefore, the common difference is 6.
