Snúið ykkur að kaflanum hér fyrir neðan og svarið spurningunni á sama máli og kaflan: Passage: Next one needs the sequence of forward differences between 1, 2, 3, 4,...; this is just 1, 1, 1, 1,.... The first element of this sequence is labeled Δa0. Euler transformation also depends on differences of differences, and higher iterations, but all the forward differences between 1, 1, 1, 1,... are 0. Euler transformation of 1 − 2 + 3 − 4 +... is then defined as Question: Hvað er Euler transformation háð?
Munur á munur, og hærri endurtekningar, en allir fram á milli munur 1, 1, 1, 1,... eru 0
