Note that the proportion of prime terms has a tendency to increase. For example,
1 from the first 20 terms; 6 from the first 40 terms; 16 from the first 60 terms; 34 from the first 80 terms; 53 from the first 100 terms; 90 from the first 140 terms. We conjecture that this proportion asymptotically tends to 1.
