What is the next number in the number pattern 1 5 10 14 28?

To determine the next number in the sequence 1, 5, 10, 14, 28, we need to identify the pattern or rule governing the sequence. By examining the differences between consecutive numbers, we can see that the pattern involves adding consecutive prime numbers: 4 (2+2), 5 (3+2), 7 (5+2), 11 (7+4). Therefore, the next number in the sequence would be 28 + 11 = 39.
