Try with below code: static void Main( string [] args) { int [] arr = { 1 2 3 4 5 6 6 7 6 5 4 3 7 8 8 8 4 3 2 8 }; int spliter = 2; // Take it from console int [] tempArr = new int [spliter]; int index = 0; while (index { for ( int idx = 0; idx { tempArr[idx] += arr.Skip(index).Take(2).Sum(); index += 2; } } for ( int idx = 0; idx { Console.WriteLine((idx + 1) +  value is:  + tempArr[idx]); } }

Hi Pruthvi Please try below code - int[] arr = { 1 2 3 4 5 6 6 7 6 5 4 3 7 8 8 8 4 3 2 8 6 5 3 4 }; int split = 3; int sum = 2; int[] res = new int[split]; int i = 0; int j = 1; for (int k = 0; k { res[i % split] = res[i % split] + arr[k]; if (k == ((j * sum) - 1)) { j++; i++; } }
