It's like what if I say that 1+2+3+4+5+6+ .... We say that it's represent the value of S.
We also say that 1+ (2+3+4) +(5+6+7) +(8+9+10) + ... Represent the value of S
Now we get that 1 + 9 +'18 ,+27 + 36 ... Is the value of S
That the same as saying as 1+ 9(1 +2 +3+4+5+6+....) Because I rewrote it that way would that still represent the value of S?
We would have 1+9(S) is S. (Or just let's call it a P or something )
So that would mean that 1 is the same as -8S
By that logic S has the value of -1/8
If we rewrite the sum of value of S as 1+2 + 5(1 +2+3+4+5+6...) We would still end up with 3+5(S) is S, and S = -1/8.
