Remember that recursion --has a stop case ... maybe if n is 0 -- has a step case ... to get the sum of 25 integers you might need to get the one of 24 integers and add them to 25.

a psudo code if you wish fun sum ( parameter : n ) if n <= 0 return 0 else return n + sum(n-1) this expands to n+sum(n-1) n+ n-1 + sum(n-1-1) n+n-1 + n-2 +sum(n-1-1-1) .....
