The point..........my point is this............it is like exponents..............................square roots..........1/2............cube roots..........and exponents.........like 2 squared or 2 cubed are reverse processes of each other....


I am particularly concerned about these two sums:
x=012x=1+12+14...=2

and

x=11x=1+12+13...=

Now, I know and I understand the proofs that say the first sum converges to two and the second one is divergent. ( you probably shouldn't equate a divergent series like that ).
But on an intuitive level, what separates these two sums in such a way, that their limits are so drastically different?
Both sums add very small numbers in the end ( e.g. 110000000000 ), yet one always stays smaller than two and one goes way beyond that. You would think ( again, on an intuitive level, the math is clear) that the numbers become so small that there is a certain number that doesn't change anymore (significantly).
For example:

x=11001x=ca.5
