## Growth and Decay

Summary

The content focuses on solving growth and decay word problems, a rare but potential question type on the GRE, involving populations or samples that increase or decrease over time.

- Growth and decay problems might involve natural growth of populations or radioactive decay, among other scenarios.
- You do not need specialized scientific knowledge to solve these problems; all necessary mathematical information is provided within the question.
- The basic approach involves being given a starting value and a multiplier or divisor for a fixed time interval, with the task to calculate the resultant amount after a certain period.
- Solving these problems requires taking the calculations step by step, using the given time interval as a guide to incrementally determine the final amount.
- Examples include calculating the remaining mass of a radioactive isotope after a set period and determining the size of a bacteria population after several growth intervals.
