ser3sub.4	|- ( ( ph /\ k e. ( ZZ>= ` M ) ) -> ( H ` k ) = ( ( F ` k ) - ( G ` k ) ) )

Assertion

Ref	Expression
ser3sub	|- ( ph -> ( seq M ( + , H ) ` N ) = ( ( seq M ( + , F ) ` N ) - ( seq M ( + , G ) ` N ) ) )

Proof of Theorem ser3sub

Dummy variables w x y z are mutually distinct and distinct from all other variables.
