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 of the first 4 composite numbers is 27
63
The sum of the first four prime numbers is 17.
The sum of 5 composite numbers can be either composite, or prime, depending on the case.
The first five composite numbers are 4, 6, 8, 9 and 10; and their sum is 37 also 28
The four smallest three digit composite numbers are: 100, 102, 104, 105 with sum 411.
They add up to: 254
The sum of the first four prime numbers is 17.
The sum of the composite numbers between 1 and 50 is 936.
The answer depends on A.
There are four of each.
The sum of the composite numbers that are less than 8 is: 4+6 = 10
