Even numbers are numbers divisible by 2
Examples of even numbers are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26 etc, thus simply adding 2 to preceeding number to get succeeding number
x:x is read as x is such that x is ....
Since x is greater than two, means 2 is not inclusive
Since x is less than or equal to twelve, 12 is inclusive. Or means can be that or that. So either less than twelve or equal to twelve
Hence the list of x is {4,6,8,10,12}
