I don't think that's correct...well at least from whats described ie you said each result element is the sum of all the elements after it including itself. Therefore when you get to 3 you should sum up 3 and 8. Since 8 is the last element it becomes the result.
What you have just described is a different problem altogether.
Thank you for the advice, to be honest, this is my first time doing a programming task for a mentoring session. (I'm a fresh graduate from a vocational high school, LMAO no body care). 
So I need to follow the task description or an example of the task (?)
