The first five composite numbers are 4, 6, 8, 9 and 10; and their sum is 37 also 28
12
Ok
32
32+33+34+35+36 (31 is a prime number) = 170
Not always, for example 2 + 3 = 5 where 5 is also a prime number.
The sum of any two prime numbers may or may not be prime. The sum of the two prime numbers 2 and 3 is the prime number 5, and the sum of the two prime numbers 5 and 7 is the composite number 12.
The sum of these composite numbers, including 100, is 3989.The sum of all numbers between 1 and 100 is 5,050. From this we need to subtract the sum of 1 plus all the prime numbers below 100. The sum of the primes is 1,060. Subtracting (1 + 1060) or 1,061 from 5,050 yields 3,989.
The first 5 composite numbers are 4, 6, 8, 9, and 10. 4 + 6 + 8 + 9 + 10 = 37, so their average is 37/5, or 7.4.
The sum of 5 composite numbers can be either composite, or prime, depending on the case.
The sum first Prime number is (2 + 3 + 5 + 7 + 11 + 13 + 17 + 19 + 23 + 29 ) = 129 The sum of the first composite numbers is (4 + 6 + 8 + 9 + 10 + 12 + 14 + 15 + 16 + 18) = 112 The difference is 129 - 112 = 17 !!!!!
32+33+34+35+36 (31 is a prime number) = 170
The sum of the first 5 numbers is 15. 1+2+3+4+5=15
2 composite numbers whose prime factorization have a sum of 10 are 30 (2+3+5=10) and 21 (3+7=10).
The sum of the first two prime numbers is 5.
The first five prime numbers are 2,3,5,7,11. The sum of the first five prime numbers is 28.The sum is: 2+3+5+7+11 = 28
Not always, for example 2 + 3 = 5 where 5 is also a prime number.
The sum of the first 100 even numbers is 10,100
The first three odd numbers are 1, 3, and 5. Their sum is 1 + 3 + 5 = 9.
The sum of any two prime numbers may or may not be prime. The sum of the two prime numbers 2 and 3 is the prime number 5, and the sum of the two prime numbers 5 and 7 is the composite number 12.
it is 5
