Specific values from a list, awk

Hello together!

I have a list like this
Code:
1 3
2 5
3 7
4 2

Now I want to take the average of the second column and multiply it by the difference of the first and last value of the first column.
I posted an similar thread, but now I wonder how I can tell awk in an easy way to take specific values (In this case the first and the last of the first column)

The awk script should do this mathematical :
Code:
 print ( (3+5+7+2)* (4 - 1) )

Thanks a lot!

Björn

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
