Answer:
This is an geometric sequence with a common ratio <em>r</em> of 1/2
Step-by-step explanation:
When you find out <em>r</em>, you realize the ratio between the numbers to be dividing by 2, or 1/2. Since it is <em>r</em> and not common difference <em>d</em>, it is an geometric sequence.
Integers: -6/2, -|7|, |-8| - 2, |-15|, 15/3
Non-Integers: 3+5/2, 9-5/8, 0.7
