Find the missing number in the series? 3, 11, 27, ?, 123

The differences between the terms are powers of 2 multiplied by an increasing integer. The first difference is 11 - 3 = 8, which is 4 * 2^1, and the second difference is 27 - 11 = 16, which is 4 * 2^2. The next difference must be 4 * 2^3 = 32, making the missing term 27 + 32 = 59. This is confirmed because the difference to the next term is 123 - 59 = 64, which is 4 * 2^4.
