Theorem faclimlem1 34782

Description: Lemma for faclim 34785. Closed form for a particular sequence. (Contributed by Scott Fenton, 15-Dec-2017.)

**Assertion**
Ref	Expression
faclimlem1	⊢ (𝑀 ∈ ℕ₀ → seq1( · , (𝑛 ∈ ℕ ↦ (((1 + (𝑀 / 𝑛)) · (1 + (1 / 𝑛))) / (1 + ((𝑀 + 1) / 𝑛))))) = (𝑥 ∈ ℕ ↦ ((𝑀 + 1) · ((𝑥 + 1) / (𝑥 + (𝑀 + 1))))))

Distinct variable groups: 𝑛,𝑀 𝑥,𝑀

Proof of Theorem faclimlem1 Dummy variables 𝑎 𝑏 𝑘 are mutually distinct and distinct from all other variables.
