![Example 1
Let (sn) be the sequence defined by sn = n²(-1)". The positive terms
of this sequence comprise a subsequence. In this case, the sequence
(Sn) is
(-1, 4, -9, 16, -25, 36, -49, 64, . . .)
and the subsequence is
(4, 16, 36, 64, 100, 144,
More precisely, the subsequence is (Sn)kEN where n=2k so
that sn=(2k)² (–1)2k=4k². The selection function o is given by
o(k)=2k.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe5f558a7-14fc-4024-84d6-4debb1adc6f6%2F7b34f507-50eb-4585-8f2a-99eddeab5497%2F3swbpef_processed.png&w=3840&q=75)
