The question is:
The answer is none of above.What is sum of five odd numbers
b)divisible by three
c)divisible by 5
d)a prime number
e)non of the above
But i think the answer should be divisible by 5 because:
sum of x,x+2,x+4,x+6,x+8 is 5x + 20 which is always divisible by 5. Could anyone tell me what i am doing wrong here?
