If the greatest integer in List G is 7, what is the sum of all negative integers in List G?A. -36B. -32C. -28D. -24E. -20Since the sum of n consecutive integers equals the mean multiplied by the number of terms n; and since the mean of any evenly spaced set (like these) equals the median which is obviusly equal to 0,even the sum of the list G will be 0Now we have to subtract the sum of the positive integers which is : mean*7, (1+7)/2 *7= 28sure 0-28=-28Correct answer is C.

If the greatest integer in G has 15 consecutive integers.The greatest integer is 7.=> 0 to 7 = (Total 8 integers).=> -7 to -1 = -( 7+6+5+4+3+2+1).=> Sum of 'n' natural numbers: $$\frac{n(n+1) }{ 2}$$=> $$\frac{7 * 8 }{ 2}$$ => 28.Sum of all negative integers in List G = -28Answer C
