Question

If a single pane of a certain type of glass blocks 3% of the light passing through it, what percent of the original light will be present after the light has passed through 10 panes

Answer 1

Isn't this a geometric progression?

an=100(.97)^n n=0, 1,2,3,4,5...

Find the nth term.
An=100r^(n) where r=.97
