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?
i think post reply ''19'' is not correct
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.
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?
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.
even though the sequence doesn't converge.
