Theorem incsequz2 36920

Description: An increasing sequence of positive integers takes on indefinitely large values. (Contributed by Jeff Madsen, 2-Sep-2009.)

**Assertion**
Ref	Expression
incsequz2	⊢ ((𝐹:ℕ⟶ℕ ∧ ∀𝑚 ∈ ℕ (𝐹‘𝑚) < (𝐹‘(𝑚 + 1)) ∧ 𝐴 ∈ ℕ) → ∃𝑛 ∈ ℕ ∀𝑘 ∈ (ℤ_≥‘𝑛)(𝐹‘𝑘) ∈ (ℤ_≥‘𝐴))

Distinct variable groups: 𝑘,𝐹,𝑚,𝑛 𝐴,𝑘,𝑚,𝑛

Proof of Theorem incsequz2 Dummy variables 𝑝 𝑞 are mutually distinct and distinct from all other variables.
