Theorem ruclem12 14970

Description: Lemma for ruc 14972. The supremum of the increasing sequence 1^st ∘ 𝐺 is a real number that is not in the range of 𝐹. (Contributed by Mario Carneiro, 28-May-2014.)

**Hypotheses**
Ref	Expression
ruc.1	⊢ (𝜑 → 𝐹:ℕ⟶ℝ)
ruc.2	⊢ (𝜑 → 𝐷 = (𝑥 ∈ (ℝ × ℝ), 𝑦 ∈ ℝ ↦ ⦋(((1^st ‘𝑥) + (2^nd ‘𝑥)) / 2) / 𝑚⦌if(𝑚 < 𝑦, ⟨(1^st ‘𝑥), 𝑚⟩, ⟨((𝑚 + (2^nd ‘𝑥)) / 2), (2^nd ‘𝑥)⟩)))
ruc.4	⊢ 𝐶 = ({⟨0, ⟨0, 1⟩⟩} ∪ 𝐹)
ruc.5	⊢ 𝐺 = seq0(𝐷, 𝐶)
ruc.6	⊢ 𝑆 = sup(ran (1^st ∘ 𝐺), ℝ, < )

**Assertion**
Ref	Expression
ruclem12	⊢ (𝜑 → 𝑆 ∈ (ℝ ∖ ran 𝐹))

Distinct variable groups: 𝑥,𝑚,𝑦,𝐹 𝑚,𝐺,𝑥,𝑦 Allowed substitution hints: 𝜑(𝑥,𝑦,𝑚) 𝐶(𝑥,𝑦,𝑚) 𝐷(𝑥,𝑦,𝑚) 𝑆(𝑥,𝑦,𝑚)

Proof of Theorem ruclem12 Dummy variables 𝑧 𝑛 𝑘 are mutually distinct and distinct from all other variables.
