Answers:

number of worms:   x (James)              x+2 (John)              x + 2 + 3 (Tom)

Total = 28 = x + x + 2 + x + 2 + 3

28 = 3x + 2 + 2 + 3

28 223 = 3x => 21 = 3x => x=7 (that is how many worms James caught).

So James caught 7 worms, John (who caught two more than James) caught 9 worms, and Tom (who caught 3 more than John) caught 12 worms.
