What is the sum of the odd numbers up to 500?
The sum of the odd numbers (from 1) up to to 500 is 62500. The sum of an arithmetic series is given by: sum = 1/2 x number_in_series x (first + last) For the odd numbers from 1 to 500, there is: number_in_series = 250 first = 1 last = 499 which gives the sum as: sum = 1/2 x 250 x (1 + 499) = 62500.
How do you figure out the sum of the first 25 odd numbers without doing 1 3 5 and so on?
The sum of the first n odd numbers is n squared. 25 x 25 = 625
What algebraic expression represents the sum of two odd integers?
x+x+2 The x is the first integer and x+2 is the odd integer since odd numbers are every other number. so the sum therefore is x+x+2
How do you work out the sum of the first 100 odd numbers?
This is very easy. Simply square the number: 100 squared (100 x 100) = 10,000. So, the sum of the first 100 odd numbers is 10,000.
The sum of two consecutive odd numbers is 44?
Let's call the first odd number x. Since the numbers are consecutive, the second odd number would be x + 2. The sum of the two numbers is 44, so the equation would be x + (x + 2) = 44. Solving this equation yields x = 21, which means the two consecutive odd numbers are 21 and 23.
