Extracting intervals from an array to create a new array

Hi,
I'm trying extract a series of intervals from an array to create a new array, where it is the sum of these individual intervals.
For example I have a 100x1 array, would like to divide it in such that every 5 number is in a group. Then a new array should be created, which contains the sums of all these intervals (which should end up being a 20x1 array).
I've tried to solve it with a "for function", but can't really seem to get it working. Any help or hints would be highly appreciated :)
Best regards
