ATQ, Sum of S1, S2, S3, and S4 16 x 4 64 4x Sum of S1 and S2 12 x 2 24 2x Sum of S3 and S4 12 3x 2 24 6x Now, setting the equations equal 24 2x 24 6x 64 4x Or, x 4 Sum of S3 and S4 24 6 4 48 S3, S4 23, 29 Hence, None of these pairs sum to 48. Therefore, there is no pair of consecutive primes summing to 48 in the standard set of known primes.

and S4 is (16 + x). If the average of S1 and S2 is (12 + x) and the average of S3 and S4 is (12 + 3x), then find S4.
