Option lD = 8473] If (n) 1S a sequence such that Xn 0, for every n E N and if lim,-o ((-1)"Xn) eio one of the following statements is true? 23) Question ID = 2141] The sequence (x,) is a Cauchy sequence. [Option ID = 8562] The sequence (x,) is not a Cauchy sequence. [Option ID = 8564] The sequence (x,) is unbounded [Option ID = 8563] The sequence (x7) is divergent. [Option ID = 8561] Correct Answer - The sequence (x,) is a Cauchy sequence. [Opton ID 8562] ********* ********* Ifn > 2, then n- 5n3+ 4n is divisible by Question ID = 2113] 1. 80 [Option ID = 8449] 2. 120 [Option ID = 8451] 3. 100 [Option ID = 8450] 4. 125 [Option ID = 8452] Correct Answer- 120 [Option ID = 8451] -- -- ---------- ********** 25) Let S-n23+ Then S equals [Question ID = 2140] (2, 3] [Option ID = 8558] [Option ID = B560] 12, 3).
