It is 50*51/2 = 1275.

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.
(n)( n+1)/2 where n = 50. (50 x 51)/2 = 2,525
rearrange 1 to 50 so that you see this pattern: 50 = 50 1+49 = 50 2+48 = 50 ... 24+26 = 50 25 = 25 then add this up: 25 x 50 + 25 = 1275
1/2, or 50%.1/2, or 50%.1/2, or 50%.1/2, or 50%.
sum of n natural number is n(n+1)/2 first 50 number sum is 50(50+1)/2 = 1275

Using the formula for the sum of an arithmetic sequence;Sum = 1/2*n [n is the total number of terms] *(2a [a is the value of the first term] + (n-1) * d)[d is the common difference between each term]So the formula looks like this: Sum = 1/2*n (2a+(n-1)*d)n = 50 because there's 50 odd numbers in a hundred and 50 even numbers (50+50=100)a = 1d = 2So inputting the values gives:Sum= 1/2*50 (2*1+(50-1)* 2)Sum= 25*(2+49*2)Sum= 25*(2+98)Sum= 25*(100)Sum= 2500Answer= 2,500
Here are the factor pairs of 50:1 and 502 and 255 and 10Now add them up: 1 + 50 + 2 + 25 + 5 + 10 = 93
Sum of 1st n even numbers: count*average = n * (2 + 2*n)/2 = n * (n+1) Sum = 50 * (2+100)/2 = 50*51 = 2550
(n)( n+1)/2 where n = 50. (50 x 51)/2 = 2,525
1 + 2 + 5 + 10 + 25 + 50 = 93
Sum of numbers from 1 to 100:(1+100) + (2+99) + (3+98) + (4+97) + ... + (49+52) + (50+51) =50 pairs, each pair adds up to 101= (50 x 101)= 5,050
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.
