In our $5\times 5$ grid we can see there are $8,9$ and $8$ of the letters $\text{P},\text{Q},$ and $\text{R}$'s respectively. We can see our pattern between each is $x,x+1,$ and $x$ for the $\text{P},\text{Q},$ and $\text{R}$'s respectively. This such pattern will follow in our bigger example, so we can see that the only answer choice which satisfies this condition is $\boxed{133\text{ Ps, }134\text{ Qs, }133\text{ Rs}}.$
