2, +2= 4, +2= 6, +2= 8, +2= 10, +2= 12

# Description

This command displays the even numbers from 2 through 12. The Separator parameter is used to add the string , +2= (comma, space, +, 2, =, space).

# EXAMPLE 3

C:\PS>write-host (2,4,6,8,10,12) -Separator ", -> " -foregroundcolor DarkGreen -backgroundcolor white
