31, 7, 5
The sum of the five smallest prime numbers is 18.
They are: 31+37+41+43+47+53+59 = 311The sum of all prime numbers between 30 and 60 is 311.
The given numbers of 15 and 35 are not prime numbers but they add up to 50
The only way for three prime numbers to have a sum of 42 is if one of the prime numbers is 2, as 2 is the only even prime number. The other two prime numbers must add up to 40, which can only be achieved by 3 and 37. Therefore, the three prime numbers that have a sum of 42 are 2, 3, and 37.
41 and 43
41,2
43 and 19
In order to find three different prime numbers that sum up to 40, we need to identify the possible combinations. The only prime number that is even is 2, so one of the prime numbers must be 2. The other two prime numbers that add up to 38 can be 19 and 17. Therefore, the sum of the three different prime numbers that add up to 40 is 2 + 19 + 17 = 38.
To find the sum of the numbers between 43 and 87 inclusive, we need to add up all the numbers between them, including 43 and 87. There are a couple of ways to do this, but one common method is to use the formula for the sum of an arithmetic sequence: S = (n/2)(a + b) where S is the sum, n is the number of terms, a is the first term, and b is the last term. In this case, we want to find the sum of the numbers between 43 and 87, so: a = 43 b = 87 To find the number of terms, we need to count how many numbers are between 43 and 87, inclusive. There are 87 - 43 + 1 = 45 numbers. Therefore, the sum is: S = (45/2)(43 + 87) = 2025 So the sum of the numbers between 43 and 87 inclusive is 2025.
2 and 43 (they are the only ones)
Not including 1 as a prime number. Prime Numbers are ones that can only divide by themselves and 1 with no remainder. therefore the first 15 are: 2,3,5,7,11,13,17,19,23,29,31,37,41,43,47. 2+3+5+7+11+13+17+19+23+29+31+37+41+43+47 = 359
13, 17, and 13. 13+13 = 26 + 17 = 43
