Tirohia te whiti i raro nei, ka whakahoki i te pātai i muri i roto i te reo ano rite te whiti: Passage: Next kotahi hiahia te raupapa o ngā rerekētanga mua i waenganui i 1, 2, 3, 4,...; ko te tika tenei 1, 1, 1, 1,.... Ko te huānga tuatahi o tenei raupapa kua tohua Δa0. whakawhitinga Euler hoki tei runga i ngā rerekētanga o ngā rerekētanga, me te iterations teitei, engari nga rerekētanga mua katoa i waenganui i 1, 1, 1, 1, 1,... he 0. te whakawhitinga Euler o 1 − 2 + 3 − 4 +... Kei te ka tautuhia rite Pātai: He aha whakawhitinga Euler tei runga i?
rerekētanga, me te iterations teitei, engari nga rerekētanga whakamua katoa i waenganui i 1, 1, 1, 1,... he 0
