You begin with 5 seeds.
These 5 seeds germinate, and for each of the original 5, we get 5 more seeds, for a total of 25 seeds.
Use the same approach to determine how many seeds would be produced if these 25 seeds all germinated and each produced 5 more seeds.

What is the formula for this?

5:  original number of seeds, when n=0 (n germinations):  5*5^0
25:                                                                                       5*5^1
125                                                                                       5*5^2

and so on.   

Can yo u use this info to find the number of seeds produced after 7 germinations?
