Arithmetic:
3 ants start to go up a wall. Every minute, 3 more ants follow in their footprints. How many ants will have climbed up the wall after 2 hours?

Geometric:
A book costs $30. The book loses 25% of its value each year. After 4 years, how much value will the book have lost? (note: the first # of the series is not 30)
