In this exercise, you will analyze building height variation in a city where buildings of different ages coexist. As in the example in chapter 3, suppose that the city grows outward by one block each year. Block 0 is built inyear 0, block 1 is built in year 1, block 2 is built in year 2, and so on. Suppose also that butldings are torn down and replaced after standing for 4 years. Buildings built in year 0 are replaced in year 4, buildings built in year 1 are replaced in year 5, and so on Derive the city's building-age pattern in year 7, when it has a radius of 7 blocks (0-7). Once the age pattern is derived, write down the year in which buildings in each block were built Fill in the following table Block Age 0 3 4 4 6
