Explanation

17 is the sum of four consecutive prime numbers: 2 + 3 + 5 + 7 = 17. These are the first four prime numbers. Checking other options: 11 is not the sum of four consecutive primes, 13 is not (3 + 5 + 7 + 11 = 26), and 23 is not either. 17 holds this unique property. This is a specific number theory fact about prime numbers.
