Question

 Lisa places 1 flower in the first vase, 3 flowers in the second vase, 7 flowers in the third vase, 15 flowers in the fourth vase, and so on. Write the function

Answer 1

Let v = vase #, running from 1 et seq.

 

# of flowers in vase v = 1 + 2(v-1) or 2v -1.

 

F(v) = 2v - 1 where v = vase #.  I assume that vase # 999 is a giant tub.
