Which value is equal to the sum of the first (24) natural numbers?

Answer and explanation

Correct answer: 300

The sum of the first \(n\) natural numbers is \(\frac{n(n+1)}{2}\). Substituting \(n=24\), we get \(\frac{24\times25}{2}=12\times25=300\). Therefore, 300 is the correct option. Although 288 is close, it is not obtained from the formula. Exam tip: In such questions, use \(n(n+1)/2\) and divide the even factor by 2 first.
