the answer of the first 4 composite numbers is 27
The sum of 5 composite numbers can be either composite, or prime, depending on the case.
The sum of the first seven positive INTEGERS is 28. The sum of the fisrt seven positive numbers is infinitesimally small.
You can figure out the "composite numbers" from any table of primes - all the positive integers that are not prime numbers are composite (the number one should also be excluded). The first four composite numbers are:4, 6, 8, 9
The answer depends on A.
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 !!!!!
The sum of the composite numbers that are less than 8 is: 4+6 = 10
The three composite numbers are 28, 30 and 32. Their sum is 90.

The sum of any two prime numbers is not always a composite number. The sum of 2 and 11 is 13, and 13 is a prime number, not a composite number.
The sum of two prime numbers will be composite unless one of the prime numbers is 2.
the answer is 49.
