Step 1: Recall the formula for the sum of the first $n$ natural numbers.

$S_n = \frac{n(n+1)}{2}$

Step 2: Substitute $n = 50$ into the formula.

$S_{50} = \frac{50(50+1)}{2}$

Step 3: Simplify inside the parentheses.

$S_{50} = \frac{50 \times 51}{2}$

Step 4: Multiply the numbers in the numerator.

$S_{50} = \frac{2550}{2}$

Step 5: Divide by 2.

$S_{50} = 1275$

$\boxed{1275}$
