Explanation

The pattern is: 6*2+1=13, 13*2-1=25, 25*2+1=51, 51*2-1=101, 101*2+1=203.

AI explanation

The series follows a mixed multiplication pattern of multiplying by 2 and alternately adding 1 or subtracting 1. The second term is 13 because 6 * 2 + 1 = 13, the third term is 25 because 13 * 2 - 1 = 25, the fourth term is 51 because 25 * 2 + 1 = 51, and the fifth term is 101 because 51 * 2 - 1 = 101. Applying the same logic, the next term is 101 * 2 + 1 = 203. The next term is 203.
