chasing LEDs

I am to make a simple circuit which outputs 3 LEDs chasing each other. I mean one LED lights after the other. After reaching the 3rd(last LED), the first will light again and the sequence continues. I was thinking of using a 555 timer and 4017 counter. Luckily, there was already a previous thread the same with mine but the output was to drive ten LEDs which will light one after the other.

To drive only 3 LEDs, what I will have to do is connect pin 15 to pin 7 of 4017??? Will that be right?

Yes, the 4017 will immediately be reset when it tries to count to four if the pin 15 is connected to pin 7.
But pin 15 should also reset the 4017 when it is first powered.

We recently had a thread about using transistors to make a 3 LEDs Chaser https://www.electro-tech-online.com/threads/astable-circuit-with-three-transistors.123567/ . A video of it working is posted there. Here is its simple schematic:

I have already watched the video sir. But the transition is too fast. Can I control the speed?

Just increase the capacitor values to slow the chase sequence.
