The formula for the sum of an arithmetic sequence is ((first number) + (last number)) x (how many numbers) / 2, in this case, (1 + 100) x 100 / 2.

6 and 28
All of them are divisible by 1.
Add them all together then divide the sum by 100 (move the decimal point two places to the left).
The sum of the all prime numbers from 1 to 100 is 1,161
I wrote out all the factors of all the numbers from 1 to 100 and counted them.
The sum of all the odd numbers from 1 through 100 is 10,000

The prime numbers from 75 through 100 are: 79, 83, 89, 97
All of them are divisible by 1.
Add them all together then divide the sum by 100 (move the decimal point two places to the left).
100
90. all the numbers from 10 through 99
The sum of the first "n" numbers is equal to n(n+1)/2.
I suggest you use the formula for an arithmetic series to calculate that.
