It is both wrong and enourmously confusing to students. To get a better picture of how this percentage-based growth affects things, we need an explicit form, so we can quickly calculate values further out in the future. Answer: Arithmetic growth is usually additive, e.g. Thomas Malthus claimed that the worlds population (i.e., in the late 18th and early 19th centuries) was growing geometrically; though food production was only growing arithmetically (i.e., arithmetic progression). The exponent in geometric sequence formula is always integer. So if you are only living on one dimension, then you need to expand it to four dimensions. \\ Later in the chapter, we will develop a continuous-time model, properly called an exponential model. Asking for help, clarification, or responding to other answers. It's also applicable . Which finite projective planes can have a symmetric incidence matrix?
