Is it true that geometric progressions are \leq arithmetic?

Doesn't seem a far shot. We know that arithmetic mean is greater or equal than geometric mean, perhaps applying that you could get to your result. Are we assuming finiteness or not?

I am wondering if GP $\leq$ AP

So your question seems to be whether the sum of any arithmetic progression is greater than or equal to the sum of any geometric progression. That is not the case. For example, $$1,\,3,\,5$$ is an arithmetic progression and $$2,\,4,\,8$$ is a geometric progression. But, $$1+3+5=9\mbox{ and }2+4+8=14$$
