Final answer:
The two possible values for variable n are -0.5 and -3.5, which are both exactly 1.5 units away from -2 on a number line.
Step-by-step explanation:
The question asks us to identify the possible values of a variable n that is 1.5 units away from -2 on a number line. To find these values, we can visualize the number line and mark the point at -2. Since the distance can be in either direction, we add and subtract 1.5 from -2.
If we add 1.5 to -2, we get -0.5 as one potential value for n. This is moving to the right on the number line from -2. Alternatively, if we subtract 1.5 from -2, we get -3.5 as the second possible value for n. This is moving to the left on the number line from -2.
Therefore, the two possible values for n are -0.5 and -3.5.
