I am new to Mathematica and I am trying to solve this problem of counting the number of binary strings of a certain length m, as far as no consecutive 1s are there.
For instance m = 3, my recurrence relation should give 5 i.e. 000, 001, 101, 100, 010.
I started like this with initial seeds: n > 0; a[ 1] = 1, a = 3, a = 5 and then in RSolve I did:
Is there a better way to improve it so that I can use the output in a plot? Currently, I cannot as my solution says it cannot be used as function.
