What is the sum of the first 5 composite numbers right after 30?
32+33+34+35+36 (31 is a prime number) = 170
Is the sum of two prime numbers can be composite?
Well, honey, let me break it down for you. The sum of two prime numbers can definitely be composite. Take 2 and 3 for example - both prime, but when you add them together, you get 5, which is still prime. But toss in 2 and 4, both prime, and you get 6, which is as composite as it gets. So, yes, the sum of two prime numbers can absolutely be composite.
When adding 2 prime number will the answer be prime?
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.
What is the sum of all composite numbers from 1 to 100?
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.
What is average of the first 5 composite numbers?
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.
