Search for gaps between primes where each composite is divisible by increasing integers (2, 3, 4, ...)

Surely, but $\,n!+1\,$ and $\,n!+1+n\,$ are not always both primes, as well as $\,lcm(1,\,2,\,\ldots,\,n)+1\,$ and $\,lcm(1,\,2,\,\ldots,\,n)+1+n\,$. So, my point of view is different.

An upper bound for $\,m_k=\min\,\{m\in N:\,mp_k+1\;\;is\;prime\}$
asked
Does the equation in positive integers $(n,y)\,\prod_{k=1}^n(p_k^2-1)=y^2\,$ only have the solution $(3,24)$?

 Nice Question
asked
Does the diophantine equation $\,\prod_{k=1}^n(p_k^{x_k}-1)=y^2\,$ have always at least a solution for $\,n\gt2\,$?
asked
How far ahead do we have to look after $p_n$ to be sure we find another prime $q$ such that $(p_n+q)/2$ is also prime?

A conjectured upper bound for the mean value of prime divisors inside prime gaps
You are perfectly right. I have corrected the post. Thanks.
