Theorem isumrecl 15751

Description: The sum of a converging infinite real series is a real number. (Contributed by Mario Carneiro, 24-Apr-2014.)

**Hypotheses**
Ref	Expression
isumrecl.1	⊢ 𝑍 = (ℤ_≥‘𝑀)
isumrecl.2	⊢ (𝜑 → 𝑀 ∈ ℤ)
isumrecl.3	⊢ ((𝜑 ∧ 𝑘 ∈ 𝑍) → (𝐹‘𝑘) = 𝐴)
isumrecl.4	⊢ ((𝜑 ∧ 𝑘 ∈ 𝑍) → 𝐴 ∈ ℝ)
isumrecl.5	⊢ (𝜑 → seq𝑀( + , 𝐹) ∈ dom ⇝ )

**Assertion**
Ref	Expression
isumrecl	⊢ (𝜑 → Σ𝑘 ∈ 𝑍 𝐴 ∈ ℝ)

Distinct variable groups: 𝑘,𝐹 𝑘,𝑀 𝜑,𝑘 𝑘,𝑍 Allowed substitution hint: 𝐴(𝑘)

Proof of Theorem isumrecl Dummy variable 𝑗 is distinct from all other variables.
