The answer depends on where the space would be between the first two: 3.7 and 68.3 or 3.76 and 8.3 or 3.768 and .3
94
1, 17 and 289.
There is no solution. For two numbers to add to an odd total, one of them must be even. If that number is also a prime it must be 2. But if one of the numbers is 2 and the two sum to 289, the other must be 287. But 287 is not a prime and the question required two primes to be added.
289 = 17 x 17
The prime number (factor) of 289 is: 17
289

650 + 290 = 940

Sum(X) = 37 Sum(X2) = 289 Var(X) = Sum(X2) - sum(X)2/n = 289 - 37*37/5 = 15.20
The prime factors of 289 are 17 and 17 (i.e. 289 = 17*17).
17*17 = 289
