Question

Sum of 10 consecutive whole numbers is 40. what is the sum oftheir squares

Answer 1

Let the numbers be x,x+1,x+2,x+3,x+4,x+5,x+6,x+7,x+8,x+9
So sum of x+x+1+x+2+x+3+x+4+x+5+x+6+x+7+x+8+x+9=40
10x +45=40
10x=40-45
10x=-5
x=-5/10=-1/2
As -1/2 is not a whole number
The situation is not possible
