All you need to do is work out the function behind the sequence. To generate
this particular sequence, you need 2 loops, and outer one counting from 0..2
and an inner one counting between 0..1:
for n in {0..2};
do
for m in {0..1};
do
echo "Welcome $(((n * 4) + m)) times";
done;
done;
or, in one line:
for n in {0..2}; do for m in {0..1}; do echo "Welcome $(((n * 4) + m))
times"; done; done;
