Question

Find the average of first fifty natural numbers

• A. 21.55
• B. 25
• C. 12.25
• D. 25.5

Hint:

To find the average of the first \(n\) natural numbers, use the formula \(\frac{n+1}{2}\).

Answer 1

The Correct Option is B

The formula for the average of the first \(n\) natural numbers is: \[ \text{Average} = \frac{n+1}{2} \] For the first 50 natural numbers: \[ \text{Average} = \frac{50+1}{2} = \frac{51}{2} = 25.5 \] Thus, the correct answer is \(25.5\).
