meaning of the word "this" in your last sentence is not well defined.
So if you see in a passtime magazine the sentence fill in the blanks: 2, 4, 6, xx, xx, xx you would not write 8, 10, 12? Come on Bob.
This was intended for the OP, not for you.

Sigh. You are completely missing the point. I am not asking the OP to
supply missing reasoning. I am asking him/her to explain why merely posting
a sequence of numbers without any given reasoning might constitute a proof.
With the sequence of 30 prime numbers, I asked the OP if all the terms in the infinite sequence are prime or not without calculator. Only reasoning. I have to repeat that the OP believes that the original sequence produces always prime numbers, but he is asking a proof from other people. That's why I presented this simple exercise.
