Edit: 49 is NOT a prime number, which is a square, 7^2 = 49.. 59, 79 and 89, however, are all of the record numbers which means that any one of them could be the answer to this question.. 59 = 3*10-1 +30. 79 = 5*10-1 + 30. 89 = 6*10-1 +30. Old and incorrect answer:. The answer is 49.. 19 {2x10-1} +30=49. 49 is the prime
