The sum of the first 5 numbers is 15. 1+2+3+4+5=15
The numbers are -1, 0, 1, 2 and 3.
They are: 2+3+5+7 = 17
The first three odd numbers are 1, 3, and 5. Their sum is 1 + 3 + 5 = 9.
The sum of the prime numbers from 1 to 12 is equal to 2 + 3 + 5 + 7 + 11 = 28.
The sum of -5 and 20 is 15. The distance between -5 and 20 is 25. The sum of the numbers between -5 and 20 is 180. The sum of the numbers from -5 to 20 is 195.
The prime numbers between 1 and 15 are 2, 3, 5, 7, 11, and 13. To find the sum, you simply add these numbers together: 2 + 3 + 5 + 7 + 11 + 13 = 41. Therefore, the sum of prime numbers between 1 and 15 is 41.
The sum of prime numbers between 1 and 25 is 100. 2 + 3 + 5 + 7 + 11 +13 +17 + 19 + 23 = 100
The sum of the first 5 numbers is 15. 1+2+3+4+5=15
The numbers are -1, 0, 1, 2 and 3.
1+1+1+1+1+=5 * * * * * The question did not ask for the sum of the first counting number five times! The sum of the first 5 counting numbers is 1+2+3+4+5 = 15. Such sums are known as triangular numbers.
They are: 2+3+5+7 = 17
The first three odd numbers are 1, 3, and 5. Their sum is 1 + 3 + 5 = 9.
It cannot make the sum because: if the numbers are in odd quantity there sum is always a odd number
The sum of the prime numbers from 1 to 12 is equal to 2 + 3 + 5 + 7 + 11 = 28.
12
The numbers are 5 and -4 because 5-(-4) = 9 and 5+(-4) = 1
