Explanation

The pattern is: 2*2+1=5, 5*2+2=12, 12*2+3=27, 27*2+4=58.

AI explanation

The differences between the terms are 3, 7 and 15, which follow the pattern of multiplying by 2 and adding 1. The next difference is 15 times 2 plus 1, resulting in 31. Adding 31 to 27 gives the missing term, which is 58.
