The sequence (Un)neN = (−1, −2, −3, …) is a subsequence of (Un)neN = : (0, −1, 0, −2, 0, −3, 0, −4, 0, …). Select one: O a. True, because all values in (Un)nÊN appear as values of (Un)nÊN. b. True, it corresponds to the mapping : N - → N defined by ô(n) = 2n. c. False, a subsequence must always be strictly increasing and (Un)nÊN is not increasing. d. True, it corresponds to the mapping : N → N defined by ô(n) = 2n – 1.

…).
Select one:
a. True, because all values in (Un)neN appear as values of (un)neN.
O b. True, it corresponds to the mapping : N → N defined by (n)
= 2n.
c.
False, a subsequence must always be strictly increasing and (vn)neN is not
increasing.
O d. True, it corresponds to the mapping : N → N defined by o(n) = 2n - 1.
