Thehigher the focal length (larger number), the less you will see in your image (more zoomed in). Let's look at an 18-55mm lens as an example.

I’m sure you have seen manufacturers claim something like “The 28-300mm lens has a field of view equivalent to a focal length of 42-450mm in 35mm format”, which is a correct way of saying it.
