Consecutive even integers are -8, -6 and -4

Step-by-step explanation:

Let  be the first even integer then the next two integers will be: x+2 and x+6

According to given property, we get

[tex]x - 2(x+2) = (x+4)+8\\x-2x-4 = x+4+8\\-x-4 = x+12\\-x-x = 12+4\\-2x = 16[/tex]

Dividing both sides by -2

[tex]\frac{-2x}{-2} = \frac{16}{-2}\\x = -8[/tex]

The two next integers are:

x+2 = -8+2 = -6

x+4 = -8+4 = -4

Verification:

[tex]-8-2(-6) = -4+8\\-8+12 = +4\\4 = 4[/tex]

Hence, Consecutive even integers are -8, -6 and -4
