I just got this question. I think the answer is 5.

Answer:

The value x is 10240.

Step-by-step explanation:

The sum of the series 5(1/2)^i is x/1024.

The sum of an infinite series [tex]a_n=ar^n[/tex] is

[tex]Sum=\frac{a}{1-r}[/tex]

The given series is

[tex]a_i=5(\frac{1}{2})^i[/tex]

Here, [tex]a=5,r=\frac{1}{2}[/tex].

The sum of given series is  

[tex]Sum=\frac{5}{1-\frac{1}{2}}[/tex]

[tex]\frac{x}{1024}=\frac{5}{\frac{1}{2}}[/tex]

[tex]\frac{x}{1024}=10[/tex]

[tex]x=10240[/tex]

Therefore value x is 10240.
