The numbers are: 27 and 23
you are the number 48
Dan the detective found the number 48. The two digits are 4 and 8, which sum to 12 (4 + 8 = 12) and have a difference of 4 (8 - 4 = 4). Since 48 is a two-digit number and less than 50, it meets all the criteria given in the problem.
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..
The numbers for which the sum of its proper factors is 1 less than the number is the powers of 2; less than 50 these are: 2, 4, 8, 16 & 32.
Two numbers with a sum of 4 and a difference of 9 are -6.5 and 2.5.

15and16
The sum of the sum and difference gives twice the larger number 14 + 4 = 18 → the larger number is 18 ÷ 2 = 9 The difference of the sum and the difference gives twice the smaller number 14 - 4 = 10 → the smaller number is 10 ÷ 2 = 5 → The two numbers are 9 and 5.
4*4=16 sum of 1+6 is 7, difference is 5 so 16 is answer

sum of n natural number is n(n+1)/2 first 50 number sum is 50(50+1)/2 = 1275
