can you choose correct one for 2 of them (seperately)

Messages are sent over a communications channel using two different signals. One signal requires 2 microseconds for transmittal, and the other signal requires 3 microseconds for transmittal.
Each signal of a message is followed immediately by the next signal.
The recurrence relation for "the number of different signals that can be sent in "n" microseconds" is:
Seç.
Seç.
S(n) = S(n-2)+ S(n-3)
Using the iterative method (you compute each step by hand) calculate how many different messages can be sent in 7 microseconds? (take the initial conditions
of the recurrence relation as: So = 0 and S, = 1, S2 = 1)
7
S(n) = S(n-2)- S(n-3)
6
S(n) = S(n-1)+S(n-2)+ S(n-3)
