6, 12, 24, and 30 are even because they can all be divided by 2 and get a number with no fractions

Hope this helps!

All the numbers are even except for 15 because if you go by two's (which is the easiest way) then you go up 2,4,6,8,10,12,14,16,18, 20 and so on. This shows that 15 is a odd number.
