Answer: -20 -28.1 and -36.2

Step-by-step explanation:

20.5 - 12.4 = 8.1

12.4 - 4.3 = 8.1

4.3 - (-3.8) = 8.1

(-3.8) - (-11.9) = 8.1

(-11.9) - ([tex]n_{1}[/tex]) = 8.1

[tex]n_{1}[/tex] = -20

(-20) - ([tex]n_{2}[/tex]) = 8.1

[tex]n_{2}[/tex] = -28.1

(-28.1) - ([tex]n_{3}[/tex]) = 8.1

[tex]n_{3}[/tex] = -36.2
