    M = midpoint x_1 and x_2 = the two points (numbers) on the number line \[M = \frac{ x_1 + x_2 }{ 2 }\]

    So plug in the variables and then solve it. Tell me the answer once you get it so that I can confirm it with you.

    Let's check : \[M = \frac{ x_1 + x_2 }{ 2 } = \frac{ -7 + 12 }{ 2 } = \frac{ 5 }{ 2 } = 2.5\]

    There might've been something wrong when you figured out 5. Did you catch your mistake?
