A student states that for any positive integer n the sum of n successive integers is always divisible by n. Which of the following can be used to disprove the student's statements?
A) 1+2=3
B) 1+2+3=2x3
C) 1+2+3+4+5=3x5
D) p+(p+1)+(p+2)=3(p+1)
E)(p+1)+(p+2)+(p+3)+(p+4)+(p+5)=5(p+3)
I'm torn between A and E and not sure really how to solve.
