Question
![**Problem Statement:**
Prove that
\[
1 + \frac{1}{2} \cdot 2 + \frac{1}{4} \cdot 3 + \cdots + \frac{n}{2^{n-1}} + \cdots = 4.
\]
**Hint:**
Differentiate both sides of the equation
\[
\frac{1}{1-x} = \sum_{n=0}^{\infty} x^n
\]
and then make a substitution into the resulting equation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6a85ba4d-6f5c-41bf-97e5-182adb23b838%2Fbcc2606d-54f6-4538-a81d-d6ff29d3896c%2Fiel21hs_processed.png&w=3840&q=75)
