What sort of curve is defined by this sequence (every number is 2/3 of the previous number, but the 2/3 value is arbitrary - it could be anything between 0 and 1 exclusive)
100, 66, 44, 29, 19, 13, ...
Is is exponential? geometric?
EDIT - I rounded the numbers because adding a ton of precision only clouds the question. If this is troublesome, just pretend I didn't round the numbers and that each is exactly a multiple of 2/3 of the previous.
A sequence where $a_n=br^n$ is called geometric of ratio $r$.
