Sum even numbers from 1 to 100
I need help with this assignment. I'm very new to using UNIX/LINUX, and my only previous experience with programing anything is using python.

We are writing scripts using vim, and this one I'm stumped on.

"Write a shell script that finds and display the sum of even positive integers from 0 to 100. Use the while control structure. Show your script and a sample run.

Example: Sum of 0+2+4+6+8+10+12+14............+96+98+100. "

I can find examples of listing even and odd numbers, but everything else I seem to find is adding numbers from an input from the user, but I want to add the numbers together from a range of {1..100}.
Any help would be greatly appreciated.

NAME

       numaverage - Find the average of a set of numbers.

       | numaverage [-dhiIlmMV]    (Input on STDIN from pipeline.)

       numaverage [-dhiIlmMV]	   (Input on STDIN.  Use Ctrl-D to stop.)

DESCRIPTION

       By default numaverage will determine the average from all numbers on input.  Other options allow you to find the mode and median.

OPTIONS

	   -i  Only return the integer portion of the final sum.
	   -I  Only return the decimal portion of the final sum

	   -m  Find the mode (most occuring) of the list of numbers,
	       or when there's more than one mode, the first completed mode.
	   -M  Find the median (middle number) of the list of numbers.
	   -l  When finding the median and the count of numbers in the set is even,
	       use the lower middle number instead of the upper middle number.

	   -h  Help: You're looking at it.
