The answer is 10. 16+4=20 20/2=10.
Sum = 79*(79+1)/2 = 79*80/2 = 3160
The sum of a number plus 3 to the square root of 9 to the sum of 2 would equal -2. This is a math problem.
2
The sum is 2+14 = 16
-18
the sum of 2 plus 2 is 4/2+2=44
-6
Sum = Addition 2 + 2 = 4
The sum is 6.
The answer is 10. 16+4=20 20/2=10.
Sum = 79*(79+1)/2 = 79*80/2 = 3160
Yes. Sum of powers of 2 from 20 to 2n is (2(n + 1) - 1) or (2 x 2n) -1 So sum of 1 + 2...+ 4096 is 8192 - 1 ie 8191.
When the sum of a number plus 3 is squared, it is 11 more than the sum of the number plus 2 when squared.
if (n%2==0) sum=n/2*(n+1); else sum=(n+1)/2*n;
The sum of a number plus 3 to the square root of 9 to the sum of 2 would equal -2. This is a math problem.
