The answer is -32 Sum of -16+8 = -8 Half of -8 = -4 Sum of -5+9 = 4 Twice of 4 = 8 Product = 8*(-4) = -32
16-5= 9

The answer is -32 Sum of -16+8 = -8 Half of -8 = -4 Sum of -5+9 = 4 Twice of 4 = 8 Product = 8*(-4) = -32
The average is 8. The sum is 3 + 5 + 16 = 24, divided by 3 is 8.
There is no sequence of adds or subtracts of 5, 6, 8, 9, and 10 that sum to 1. Check it with this C++ code... for (int i=0; i<32; ++i) { int sum = 0; if (i&1) sum += 5; else sum -= 5; if (i&2) sum += 6; else sum -= 6; if (i&4) sum += 8; else sum -= 8; if (i&8) sum += 9; else sum -= 9; if (i&16) sum += 10; else sum -= 10; cout << i << " " << sum << endl; }
Factors for 16 are: 1, 2, 4, 8, 16 Sum = 1 + 2 + 4 + 8 + 16 = 31
-8.
16-5= 9
11. Sum means to add 3+8=11
15 and 16. 15= 3*5. 3+5=8 16= 4*4. 4+4=8
1.6
if Divisible by 5 = ends in 0 or 5 if Palindrome = spelled the same forwards as backwards then number begins and ends with either 0 or 5 5_5, or 0_0 Sum is divisible by 8 5+5=10 16=divisible by 8 565
The sum of 8 and 5 is 13. There is then no number with which to calculate its product.
5+2+5+16=28
