500. Since they alternate, half the numbers between 1 and 1000 are odd and the other half are even. Adding zero to the list does not change the number of odds.

97531 + 500 = 98031.
odd multiples of 7 are odd numbers.. like 7*1, 7*3,7*5..
Well, darling, the sum of the first 500 odd numbers is 500^2, which is 250,000. So, grab a calculator and impress your friends with that little nugget of math knowledge. You're welcome!

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.

There are 48/2 + 1 = 25 odd numbers in 1 to 49, inclusive.

write the number that is 500 more than the biggest number that can be formed by all the odd 1 digit number
The sum of all odd numbers, up to the odd number (2n-1) is n^2. So the sum of the first 1000 or 10^3 odd positive numbers is (10^3)^2=10^6 Now divide by 10^3 or 1000 since we have 1000 numbers so we have 10^6/10^3=1000 The mean of the first 1000 positive odd numbers is 1000 If you ask the mean of the odd numbers between, 1 and 1000, that is another problem, since there are 500 of them, the answer would be 500^2/500=500 Think of the mean of the odd numbers between 1 and 10, there are 5 of them and there sum is 25 so the mean is 25/5 or 5 **** in general, the arithmetic mean of the first n odd numbers is n^2/n or n. So that is why the number is 1000.
To find the sum of all odd numbers from 1 to 499, we can use the formula for the sum of an arithmetic series. The formula is n/2 * (first term + last term), where n is the number of terms. In this case, there are 250 odd numbers from 1 to 499. So, the sum would be 250/2 * (1 + 499) = 125 * 500 = 62,500.
