So the farther in universe we look, the faster objects appear to be speeding away from each other. But the farther we look, the further back in time we’re looking as well. So does this mean the universe is actually slowing down as it ages - nearer objects are older and not moving apart as fast as distant objects (star/galaxies)?
1. The Universe was smaller way back then.
2. Light was faster way back then................

You have a point.
But remember, it is space that is expanding.
I tend to think of space as a giant balloon that is being blown up. If you are a particle near the center of that balloon you would hardly notice. But if you are closer to the balloon itself your wiggle room would be getting increasingly more comfortable.
It’s a 4/3 PI R3 thing. And although we are not likely to be at the center of the universe our ability to look at that universe is limited to something like 13.8 billion light years in any direction. That’s what we can see. And it is a sphere inside a much bigger universe.
Don’t use any of this to answer questions on your next physics test. It is simply my imagination going crazy with only a fact or two as backup.
