Theorem seqf 10879

Description: Range of the recursive sequence builder. (Contributed by Mario Carneiro, 24-Jun-2013.)

Hypotheses

Ref	Expression
seqf.1	|- Z = ( ZZ>= ` M )
seqf.2	|- ( ph -> M e. ZZ )
seqf.3	|- ( ( ph /\ x e. Z ) -> ( F ` x ) e. S )
seqf.4	|- ( ( ph /\ ( x e. S /\ y e. S ) ) -> ( x .+ y ) e. S )

Assertion

Ref	Expression
seqf	|- ( ph -> seq M ( .+ , F ) : Z --> S )

Distinct variable groups:   x, .+ , y   x, F, y   x, M, y   x, S, y   x, Z   ph, x, y

Allowed substitution hint:   Z( y)

Proof of Theorem seqf

Dummy variables a b s t w z u v c are mutually distinct and distinct from all other variables.
