Hi rajinikanth0602

Hi;
Did you see post #32?
i will challenge that i will give 7000 rupees for solving dis problem or any important information about that sequence or range of that sequence
In exchange for the rupees I would like your acknowledgement that the problem has been solved with the proof that is in post#32, or do you require more?
As for post #19. It may be correct, I do not know. Still it is a very nice piece of work by a good man.

Hi rajinikanth0602;
By the ratio test:
By the ratio test the series diverges for all values of x.

hi bobbym any information about my question

Yes, it could.

It can be an expression in terms of x.

With a variable as the upper index yes. But with an infinity up there the sum is either a constant like 1 / 2 ( just picked as an example ) or ∞.

It is possible.
- bobbym

If you meant an expression for the closed form then it is obviously not possible. The sum will either equal a constant or infinity.

What about it?

Upper index of summation?
- bobbym
- 2012-07-23 03:08:09
How can you get a closed form? The upper index of summation is not a variable. Either it sums to some constant or it diverges.

Hi bobbym
S(sqrt(x)) is the same as the sum above. I just want a closed form. Like 1/(1-x) is the EGF for:
even though the sequence doesn't converge.
