How can I do a summation of an array, summing up several points a time, leaving me with another array?

Hello, I have been trying to find a way to do the summation of an array, by summing 19 points at a time, leaving me with another array.  I feel like this has a simple solution but I am not so sure how to do so.

Thank you.

A while loop containing Array Subset can do it.
