Seq.Fans,
Like Harvey, I find this sequence troubling at many levels.
First, why is the sequence not sorted.
Second, no term is present where the exponent of 3 exceed that of 5.
Therefore, I suggest that to get as close to what is presented, the
follow:
Name: Numbers of the form (3^(2n) + 5^(2m))/2 where m is less than or equal
to n.
data: 1, 13, 17, 313, 317, 353, 7813, 7817, 7853, 8177, 195313, 195317,
195353, 195677, 198593, 4882813, 4882817, 4882853, 4883177, 4886093,
4912337, 122070313, 122070317, 122070353, 122070677, 122073593, 122099837,
122336033, 3051757813, 3051757817, 3051757853, 3051758177, ., .
Mmca: Take[ Union[ Flatten[ Table[ (3^m + 5^n)/2, {n, 0, 14, 2}, {m, 0, n,
2}]]], 32]
Sincerely, Bob.

The first formula does not generate the terms of the sequence.
Happy New Year.
Best,
Harvey
