To find numbers with a mean of 7, we need to consider the sum of the numbers and the total count of numbers. If we have two numbers, they must add up to 14 to have a mean of 7. For three numbers, their sum must be 21. In general, any set of numbers that sum up to 7 times the count of numbers will have a mean of 7.
The two prime numbers that add up to 19 are 7 and 12. Prime numbers are numbers greater than 1 that can only be divided by 1 and themselves. In this case, 7 and 12 are not prime numbers, and there are no two prime numbers that add up to 19.
No two of those numbers add up to 17.

There are no three consecutive numbers that add up to twenty.Proof:5+6+7=186+7+8=217+8+9 = 24

Can not be done! An odd number of odd numbers will ALWAYS add up to an odd number.
if you mean what three prime numbers add up to a prime number then the answer is : 5 + 7 + 11 = 23
7 and 67.
7, 13 and 17
