Ref	Expression
clim2ser.1	|- Z = ( ZZ>= ` M )
clim2ser.2	|- ( ph -> N e. Z )
clim2ser.4	|- ( ( ph /\ k e. Z ) -> ( F ` k ) e. CC )
clim2ser2.5	|- ( ph -> seq ( N + 1 ) ( + , F ) ~~> A )

Assertion

Ref	Expression
clim2ser2	|- ( ph -> seq M ( + , F ) ~~> ( A + ( seq M ( + , F ) ` N ) ) )

Proof of Theorem clim2ser2

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