Solution

Easiest Method — Coefficient of x50

Given Expression:

(1+x)1000+2x(1+x)999+3x2(1+x)998++1001x1000

This follows a known identity that simplifies the full expression to:

f(x)=(1+x)1002

Now: The coefficient of x50 in f(x) is:

\boxed{\binom{1002}{50}}

✅ Final Answer:   \boxed{\binom{1002}{50}}



Which of the following number is the coefficient of x^{100} in the expansion of \log _e\Bigg{(}\frac{1+x}{1+{x}^2}\Bigg{)},\, |x|{\lt}1 ?
