Recurrence relation help 1. The problem statement, all variables and given/known data xn+2 − 6xn+1 + 8xn = 2n Find the particular solution. 3. The attempt at a solution I've tried "guessing" both xnp = (An + B)*2n and = (An² + Bn + C)*2n as a solution, but the calculations just don't add up and make sense. Thanks in advance for any tips and/or hints.
