The pattern for coding seems to be derived from the position of each letter in the alphabet:
D = 4, A = 1, R = 18, E = 5, which gives us the code 1083 for DARE.
F = 6, A = 1, T = 20, E = 5, which gives us the code 2093 for FATE.
For FARE, we have: F = 6, A = 1, R = 18, E = 5. This gives the code 2083.
Thus, the correct code for FARE is 2083.
