How much is the sum of the first (58) natural numbers?

Answer and explanation

Correct answer: 1711

The sum of the first \(n\) natural numbers is \(\frac{n(n+1)}{2}\). Here, \(n=58\), so \(\frac{58\times59}{2}=29\times59=1711\). Therefore, 1711 is correct. A value such as 1701 can result from an arithmetic error. Exam tip: When \(n\) is even, divide it by 2 first to simplify the calculation.
