3 and 5
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 first 8 odd numbers is 64.
The mean average of a set of numbers is the sum of the numbers divided by how many of them there are. If there are 8 numbers with a sum of 2464, their mean average is 2464 ÷ 8 = 308.
17 is a prime number. 8 and 12 are not prime numbers.

3 and 5
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 first 8 odd numbers is 64.
If you mean the 1st 8 prime numbers then they are:- 2+3+5+7+11+13+17+19 = 77
No. Not even close. Examples: 4+4=8 8+8=16 16+16=32 . . .4, 8, and 16 are not prime numbers.
no, not all prime numbers are closed under addition. why? because, when you add 2 prime numbers you will not always get a prime number. example: 5+3= 8 5 and 3 are prime numbers but their sum is 8 which is a composite number..
The sum of the first 100 even numbers is 10,100
