Theorem resqrexlemover 11021

Description: Lemma for resqrex 11037. Each element of the sequence is an overestimate. (Contributed by Mario Carneiro and Jim Kingdon, 27-Jul-2021.)

**Hypotheses**
Ref	Expression
resqrexlemex.seq	⊢ 𝐹 = seq1((𝑦 ∈ ℝ⁺, 𝑧 ∈ ℝ⁺ ↦ ((𝑦 + (𝐴 / 𝑦)) / 2)), (ℕ × {(1 + 𝐴)}))
resqrexlemex.a	⊢ (𝜑 → 𝐴 ∈ ℝ)
resqrexlemex.agt0	⊢ (𝜑 → 0 ≤ 𝐴)

**Assertion**
Ref	Expression
resqrexlemover	⊢ ((𝜑 ∧ 𝑁 ∈ ℕ) → 𝐴 < ((𝐹‘𝑁)↑2))

Distinct variable groups: 𝑦,𝐴,𝑧 𝜑,𝑦,𝑧 Allowed substitution hints: 𝐹(𝑦,𝑧) 𝑁(𝑦,𝑧)

Proof of Theorem resqrexlemover Dummy variables 𝑓 𝑔 ℎ 𝑘 𝑤 are mutually distinct and distinct from all other variables.
