Question

Accepted Answer

According to Thomas Malthus, a prominent 18th-century economist and demographer, population increases in a geometrical progression. This concept is central to his theory on population growth, which he outlined in his seminal work, "An Essay on the Principle of Population," published in 1798.

1. **Explanation for Option 1 (Geometrical progression):**
   - Malthus proposed that population, if unchecked, tends to grow exponentially, meaning it doubles over regular intervals. This type of growth is characteristic of a geometrical progression, where each term is a constant multiple of the previous one. For example, if a population starts at 100 and grows by a factor of 2, it becomes 200, then 400, then 800, and so on. This rapid increase reflects the potential for population to expand significantly over time if not constrained by factors such as food supply, disease, or other limiting factors.

2. **Explanation for why other options are incorrect:**

- **Option 2 (Arithmetical progression):**
     - Arithmetical progression refers to a sequence of numbers in which each term after the first is obtained by adding a constant difference to the preceding term. For example, a sequence like 2, 4, 6, 8, etc., increases by a constant amount (in this case, 2). Malthus argued that while population grows geometrically, food supply and resources tend to increase only arithmetically, leading to potential shortages and societal challenges.

- **Option 3 (Harmonic progression):**
     - Harmonic progression is a sequence of numbers where the reciprocals of the terms form an arithmetic progression. This type of progression is not typically associated with natural growth processes like population increase. Malthus did not use harmonic progression to describe population growth, as it does not accurately reflect the exponential nature of population expansion.

- **Option 4 (None of these):**
     - This option is incorrect because Malthus explicitly described population growth as a geometrical progression. Therefore, "None of these" does not align with Malthus's theory.

In summary, Malthus's theory of population growth is best represented by geometrical progression, as it captures the exponential nature of population increase, which he believed could outpace the growth of resources, leading to potential societal issues.
