Is 384.
And the sum of 5..? Uhh... Is it 5?
The prime number is 47 and 4+7 = 11
The prime numbers between 40 and 50 are 41, 43, 47. So their sum is 131.
The answer is 50 because its factors are 1,2,5,10,25,50. When you add up the sum of 50 you get 5 which is a prime number. Also it is between 44 and 53. :)
23 or 41
You are 54.
The question is quite ambiguous. If you're talking about all the even prime numbers between 4 and 50, then the sum is zero. No even number, except '2', is a prime number, so there aren't any between 4 and 50..

50 is not a prime number.47, 53, 59 are.Therefore 47 + 59 = 106
