The sum of the first (44) natural numbers is equal to which value?

Answer and explanation

Correct answer: 990

The sum of the first \(n\) natural numbers is \(\frac{n(n+1)}{2}\). Substituting \(n=44\), we get \(\frac{44\times45}{2}=22\times45=990\). Therefore, 990 is correct. A value such as 968 may result from incorrectly using \(44\times44/2\); the formula must include \(n+1\). Exam tip: When \(n\) is even, divide it by 2 first for quicker calculation.
