Theorem smonoord 46774

Description: Ordering relation for a strictly monotonic sequence, increasing case. Analogous to monoord 14029 (except that the case 𝑀 = 𝑁 must be excluded). Duplicate of monoords 44742? (Contributed by AV, 12-Jul-2020.)

smonoord.1	⊢ (𝜑 → 𝑁 ∈ (ℤ≥‘(𝑀 + 1)))
smonoord.2	⊢ ((𝜑 ∧ 𝑘 ∈ (𝑀...𝑁)) → (𝐹‘𝑘) ∈ ℝ)
smonoord.3	⊢ ((𝜑 ∧ 𝑘 ∈ (𝑀...(𝑁 − 1))) → (𝐹‘𝑘) < (𝐹‘(𝑘 + 1)))

Assertion

Ref	Expression
smonoord	⊢ (𝜑 → (𝐹‘𝑀) < (𝐹‘𝑁))

Distinct variable groups:   𝑘,𝐹   𝑘,𝑀   𝑘,𝑁   𝜑,𝑘

Proof of Theorem smonoord

Dummy variables 𝑛 𝑥 are mutually distinct and distinct from all other variables.
