try using induction $n=1$ $3^{2n+1}+2^{n+2}= 3^3 + 2^3 = 27+8 = 35 = 7\cdot 5$ so it's divisible by 7 $n=2$ $3^{2n+1}+2^{n+2}= 3^5 + 2^4 = 243+16 = 259 = 7 \cdot 37$ and so on... then assume that is

Group actions
Hey, We can define a group action in two ways:
1) A group G is said to act on a set X, if there exists a group homomorphism ψ : G --> S(X) [the symmetric group of X].

Can I derive the Boltzmann distribution by an invariance argument?

In statistical mechanics, the Boltzmann distribution gives the probability of a system being in state $i$ as
$$\displaystyle \frac{e^{- \beta E_i}}{\sum_i e^{-\beta E_i}}$$
