What is the Grand total of numbers from 1 to 500?

Answer 1

The grand total of numbers from 1 to 500 can be calculated using the formula for the sum of an arithmetic series: ( S = \frac{n}{2} \times (a + l) ), where ( n ) is the number of terms, ( a ) is the first term, and ( l ) is the last term. In this case, ( n = 500 ), ( a = 1 ), and ( l = 500 ). Thus, the total is ( S = \frac{500}{2} \times (1 + 500) = 250 \times 501 = 125250 ). Therefore, the grand total of numbers from 1 to 500 is 125,250.
