Even and odd numbers

• Even numbers can be divided exactly by 2. The sequence of even numbers is:
  2, 4, 6, 8, 10, 12, 14 ... and so on.

  Even numbers always end with a 2, 4, 6, 8 or 0. You can tell 3788, for example, is an even number because it ends with an 8.

• Odd numbers cannot be divided exactly by 2. The sequence of odd numbers is:
  1, 3, 5, 7, 9, 11, 13 ... and so on.

  Odd numbers always end in 1, 3, 5, 7 or 9. You can tell 4399, for example, is an odd number because it ends with a 9.
