Write the missing word or number on each line.
1. 5, 10, 15, 20
Ten plus five equals fifteen, the next number when skip counting by fives.
2. 15, 20, 25, 30
Twenty-five plus five equals thirty, continuing the skip count by fives.
3. 5, 10, 15, 20
Five is the first number when we skip count by fives starting from zero.
4. 30, 35, 40, 45
Thirty plus five equals thirty-five, fitting the skip count by fives perfectly.

Going back five from fifteen gives ten, which keeps the skip counting pattern.
