Arithmetic, Geometric, or Neither? Arithmetic
Explanation: See solution.

Practice makes perfect

We want to identify the given sequence as arithmetic, geometric, or neither. To do so we will calculate the difference and ratio between consecutive terms.

We can see above that the ratios are not the same. However, the differences are the same. Therefore, the sequence is arithmetic with a common difference of 7.
