Answer:
Approximately 338
Explanation:
Since each generation of the insect is approximately 1.5 times that of the previous generation. Therefore,
Population of insect in the first generation = 100
Population of insect in the second generation = 1.5 × 100
= 150
Population of insect in the third generation = 1.5 × 150
= 225
Population of insect in the fourth generation = 1.5 × 225
= 337.5
The population of insect in the fourth generation is approximately 338.
