BASH Please ! I need help

1. Use loops: Write a bash script to produce the output using a step-value-loop: (20%) 1, 5, 9, 13, 17, 21, 25 Your output must print the numbers horizontally (1 first and 25 last), comma separated as shown above. Hints: Look at the examples bash_sec_7.0_declaring_variables_03.sh (for precision printing) and bash_sec_09_example_7.sh as a guideline. You MUST use a step-value-loop as in the example. Other methods will get only partial credit. (YOU MUST INCLUDE THE SCRIPT FILE (.sh file) IN THE ZIP) 2.
