2. The thickness of a roll of paper where the first term is the diameter of the core of the roll and twice the thickness of the paper is the common difference.

3. Suppose you were building a picket fence on a regularly sloping path with the top of the pickets being horizontal.

4. or building a ladder with sloping sides - the length of each rung would form an AP

5. Simple interest investment:
You put P money in the bank; each year they add Pr interest to your account:
