if we look into man bash and search for Brace Expansion:
Code:
       A correctly-formed brace expansion must contain unquoted opening and closing braces, and at least one unquoted comma or  a
       valid sequence expression.  Any incorrectly formed brace expansion is left unchanged.  A { or , may be quoted with a back‐
       slash to prevent its being considered part of a brace expression.  To avoid conflicts with parameter expansion, the string
       ${ is not considered eligible for brace expansion.

One possible workaround could be:
Code:
#!/usr/bin/bash
#set -x

zz=3
yy=0
xlim=5

for i in $(eval echo {1..${xlim}}) ; do
   echo "I = $i"
   ((yy=zz * i))
   echo "Welcome $i times  $yy"
done
