- let three cosecutive numbers are : (x-1),x,(x+1)
now,
(x-1)^2+x^2+(x+1)^2=365
x^2-2x+1+x^2+x^2+2x+1=365
3x^2+2=365
x^2=(365-2)/3
x=11
therefore, the numbers are: 10, 11 , 12
smallest number is: 10 ans - 12 years agoHelpfull: Yes(0) No(2)
- Three consecutive numbers are a-1,a,a+1.
Sum of the squares of 3 consecutive number is (a-1)^2+a^2+(a+1)^2 = 365
a^2-2a+1+a^2+a^2+2a+1 = 365
3a^2+2 = 365
3a^2 = 363
a^2 = 121
a = +11 or -11
The consecutive numbers are,-12,-11,-10 & 10,11,12
the smallest number is -12. - 12 years agoHelpfull: Yes(0) No(1)
