There every circuit is mod 5 up counter not down counter

 

If you look at the ebooks here, you will find both an up counter and a down counter. Take the down counter schematic and modify it to meet your criteria.

 

Here is a block diagram simulation ....

 

I googled "mod n counter sequence" and found many results. At least one included the actual sequences. I didn't find mod 5 specifically, but you should be able to generalize and determine what you are looking for from the definitions and examples.

One note, a mod 5 down counter is just a mod 5 up counter in reverse. There are IC counters that can count both up and down. Also, the link I provided defines the terms full-sequence counter and truncated counter. Note that a mod n counter (either up or down) is a truncated counter, as the sequence does not extend for the full binary range.

 

thank you all now i am clear
