Let me present a simplified example for clarity:
Suppose you have 2 eggs, each of which gives rise to two more during every iteration. The process would go like this:
2-->2x2-->2x2x2-->2x2x2x2-->...2^n
you begin with two at step 1, then at step 2 each of the two eggs produced 2 so you have 2x2=4, then at step 3 each of the 4 eggs at the beginning of step 2 produces 2, hence you have 4x2=8. Following the pattern, the next iteration yields 8x2=16, then 32, 64.....Using exponential notation the sequence is 2^1, 2^2, 2^3, 2^4....2^n
In your original example the initial amount in 300,000. After the first iteration we have 300,000^2, because each one of the 300,000 produced 300,000, and so on. So the general formula, as above, is 300,000^n.
