Please I have a similar problem, how can I compute the sum of this infinite series:

SUM(X / (Y^X) ); where X(i)>0

$$\sum\frac{X}{Y^X}$$ X(i)>0, what is X, what is Y?

Y is a constant, while the X's are increasing from zero to infinity

Knowing only that Xn is "some" increasing sequence there is no way to find the sum.
