awk for interval midpoints and length

Question

[rbronste]

Kind of a basic awk question but just trying to take the following intervals:

chr1 10001 10150
chr1 10008 10090
chr1 10025 10207
chr1 10058 10172

And generate a file output with a single command that in the first column has the midpoint of each and in the second column next to it has the entire interval length, such as this:

10075 149
10049 82
10116 182
10115 114

Thanks.
