[seqfan] Patarn in Prime related sequence

[zbi74583.boat at orange.zero.jp]

    Hi,Seqfans
    See the graph of A096447

    I think that a property of primes looks like a random sequence.
    But almost linear sequences appear in the graph.

    The differences of the third linear sequence.

    16,42,8,28,162,230,32,28,24,18,8,42,16,50,102,28

    The ratio of the differences and terms < 0.001
    It is almost 0, so the sequence is almost linear.

    I feel strange.
    Could anyone tell me the reason why some regularity exists in this graph?
