How would I code this problem:
find the first t where abs[N-n[t]]<e where n[t+1]=n[t]^0.5+1 and n=2.
t starts at 0 and then increments in units of 1.
N and e are constants. The real problem is quite a bit more algebraically intense, but the question above encapsulates the heart of the problem. Thanks to whomever answer this. Alternatively, feel free to tell me where to even look within mathematica to find this type of answer.
