What is the sum of whole numbers 1 to 50?

The sum of whole numbers from 1 to 50 can be calculated using the formula for the sum of an arithmetic series: ( S = \frac{n(n + 1)}{2} ), where ( n ) is the last number in the series. Here, ( n = 50 ), so the sum is ( S = \frac{50(50 + 1)}{2} = \frac{50 \times 51}{2} = 1275 ). Therefore, the sum of whole numbers from 1 to 50 is 1,275.


What are the 9 odd numbers whose sum is 50 from 1 to 50?

To find the 9 odd numbers whose sum is 50 from 1 to 50, we can first calculate the sum of all odd numbers from 1 to 50, which is (50^2)/2 = 625. Next, we subtract the sum of the first 9 odd numbers (1+3+5+7+9+11+13+15+17 = 81) from the total sum, resulting in 625 - 81 = 544. Therefore, the 9 odd numbers whose sum is 50 from 1 to 50 are 19, 21, 23, 25, 27, 29, 31, 33, and 36.

What is the sum of the first 50 multiples of 6?

Why, that's just 6 times the sum of the numbers from 1 to 50 !The sum of the numbers from 1 to 50 is:1 + 50 = 512 + 49 = 513 + 48 = 514 + 47 = 515 + 46 = 51...etc. There are 25 pairs, and each pair sums to 51. So the sum of 1 ... 50 is (25 x 51) = 1,275.The sum of the first 50 multiples of 6 is (1,275 x 6) = 7,650.
