Lighting, Light Fixtures, Ceiling and Exhaust Fans - Making 2 Lights into 3 Lights

I am trying to take 2 lights operated from a single switch and install 3 lights operated from a single switch. The old configuration was from the switch to the first light:
white to white and
black to black/red.
From the last light to feed(?) was the same: white to white and black/red to black.

Now that I have 3 lights I copied the first light:
white to white and
black to black/red
and from the last light:
white to white and
black/red to black.

Question: how do I connect the wires from light 1 to light 2 and from light 2 to light 3? Do I connect black to black and red to red and white to white or should it be black/red to black/red joined and white to white?

I've tried both combinations and the lights are on with the switch off and when I turn the switch on then off the breaker kicks. Should the red be capped after the last light?

Thanks.

Where does the power come in? Where does the switch connect in?

This is one possibility of what you have.

I would think that is an accurate depiction of the layout. The switch is on one end of the wall and had wires going to light #1(B/W), then that connected to light # 2 (B/W/R), then there were the wires out (B/W) to what I am assuming to be the power in. So if this is the case, any advice on wiring R/B between the lights? From the diagam - does the red go to the black wire on the light and the black wires connect to each other, but not the light fixtures?

Yes the red is the switched power from the switch and the black is the unswitched power to the switch.

Thanks for your help! All are connected properly now and working great.
