What is te sum of the first 72 even whole numbers?

Answer 1

The first 72 even whole numbers can be expressed as 2, 4, 6, ..., 144. This is an arithmetic series where the first term (a = 2), the last term (l = 144), and the number of terms (n = 72). The sum (S) of an arithmetic series can be calculated using the formula (S = \frac{n}{2} \times (a + l)). Substituting the values, we get (S = \frac{72}{2} \times (2 + 144) = 36 \times 146 = 5256).
