Determine if the sequence below is arithmetic or geometric and determine the common difference/ ratio in simplest form 300,30,3?

This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 10.

Is a geometric progression a quadratic sequence?

A geometric sequence is : a•r^n while a quadratic sequence is a• n^2 + b•n + c So the answer is no, unless we are talking about an infinite sequence of zeros which strictly speaking is both a geometric and a quadratic sequence.
