1. I was advised by my physician to walk each day in the morning as my daily exercise. On my first day, I walked 100 m. On the second and third day, I walked 140 m and 180 m, respectively, and so on. What is the distance I walked on the 10th day if I continue my daily walk?​2. Suppose a cinema has 42 rows of seats and there are 20 seats in the first row. Each row after the first row has two more seats that the row that it precedes. How many seats are in the cinema?​3. A 25-layer of logs is being piled to be used on a construction. The uppermost layer is composed of 15 logs. The second upper layer contains 17 logs, and the third upper layer contains 19 logs, and so on.
