This is a two-step sequence. when n is even, tn = 4*tn-1 and when n is odd, tn = tn-1 + 1
If the nth term is Tn, the ratios of consecutive terms are Tn+1/Tn for n = 1, 2, 3, ... This will be a constant only for geometric sequences.
If you notice, there is a common difference between the terms: tn - tn-1 = -4 So the nth term is: tn = tn-1 - 4 For this recursive sequence to be defined though, you need something to start with as your tn-1. So start with t1= 3 and you're done.
This is what might be described as a two-step sequence or two sequences spliced together. t1 = 1 tn = - (tn-1 +1) for n = 2,4,6, ... and tn = tn-2 + 3 for n = 3,5,7, ...
