Execute 2 or more remote scripts sharing the same curl pattern, without redundancy

I use Ubuntu 16.04 and I execute a list of remote scripts that are in the same directory (a GitHub repository):

curl -s https://raw.githubusercontent.com/${user}/${repo}/master/1.sh | tr -d '\r' | bash
curl -s https://raw.githubusercontent.com/${user}/${repo}/master/2.sh | tr -d '\r' | bash
curl -s https://raw.githubusercontent.com/${user}/${repo}/master/3.sh | tr -d '\r' | bash
curl -s https://raw.githubusercontent.com/${user}/${repo}/master/4.sh | tr -d '\r' | bash
curl -s https://raw.githubusercontent.com/${user}/${repo}/master/5.sh | tr -d '\r' | bash
curl -s https://raw.githubusercontent.com/${user}/${repo}/master/6.sh | tr -d '\r' | bash

How would you cope with the awful redundancy?

I think of a for loop but I have no idea how to construct it. All for loops I've seen so far doesn't give me a clue on how to do that particular task of reusing a curl pattern (and piped output) for different files in the same remote directory.

You are more than welcome to share an example.

Update

There might be more or less than six such curl operations.
I would use any plausible way but if it requires a utility please recommend a utility available in the Debian repositories.

For two or more files you could use Unix seq:

for var in $(seq 6)
   do 
       curl -s https://raw.githubusercontent.com/${user}/${repo}/master/$var.sh | tr -d '\r' | bash
   done

Explanation:

Use the output of seq to attain a count up to 6 (as the question lists 6 curl operations).
Read the output into the variable var and use this in your curl command.
